I am successfully redirecting user after Login to a page called CustomerStart. After that query string (url) looks fine with the ssn like this
localhost:1234/CustomerStart?ssn=850406-0297
I am doing this by writing this
return RedirectToAction("Index", "CustomerStart", new {ssn = model.ssn});
But when I click a button which has been defined in the _layout like this,
<li>#Html.ActionLink("CustomerStart","Index", "CustomerStart")</li>
my query string gets empty.
I want to keep my customer to be in the same CustomerStart page both after login or if they click the CustomerStart button.
I also want to send my customer in different views when they click any of the button under the above mentioned one.
like this,
<li>#Html.ActionLink("CustomerStart","Index", "CustomerStart")</li>
<li>#Html.ActionLink("Bill","Index", "Bill")</li>
So, i need to grab the value from the query string always. But I dont know how?
I am new in MVC3 and I am totally lost.
try
<li>#Html.ActionLink("CustomerStart","Index", "CustomerStart",
new { ssn=Request.QueryString["ssn"]},
null)
</li>
<li>#Html.ActionLink("Bill","Index", "Bill",
new { ssn=Request.QueryString["ssn"]},
null)
</li>

I searched the whole web and I couldn't found any good topic which expose the proper way to do it.
I have a very simple web which I developed using Kentico 9 CMS. This web only contains two subpages and a header to navigate between those.
The "Home" subpage contains a custom form which remains connected to a SQL table which is populated every time you press submit with certain data.
On the other hand, the other page, shows the stored data by using a custom web part which connects to the DB by using BizFormItemProvider and this object is used as a layer to binding the data in a control.
Now is my point. If you see, there is a button to "Edit" a certain row and my intention is to Redirect to "Home" (which contains the form) and sending via QueryString the ID of the row attempted to edit.
I was unable to understand how can you re-fill the form with its data using an ID.
Maybe because I never worked with a CMS before, I'm looking the development such as pure ASP.NET and it could not be the correct one.
Custom
Given that your solution uses a custom form for entering the data, as well as a custom web part for listing the stored data, you will need to use a custom solution to handle the editing of data, as well.
In the custom webpart on the Home page, in a load event, you can retrieve the form data and set the values on the form controls.
protected void Page_Load(object sender, EventArgs e)
{
// Ensure that the form is not being posted back,
// to prevent entered data from being overwritten
if(!IsPostBack)
{
// Get the form item ID from the query string
var personId = QueryHelper.GetInteger("personId", 0);
if(personId > 0)
{
// Get the biz form item, and set form control values
var bizFormItem = BizFormItemProvider.GetItem(personId, "customFormClassName");
txtFirstName.Text = bizFormItem.GetStringValue("FirstName", string.Empty);
}
}
}
Similarly, when Submit is clicked, you can update the existing form item with the new data
protected void btnSubmit_OnClick(object sender, EventArgs e)
{
// Get the form item ID from the query string
var personId = QueryHelper.GetInteger("personId", 0);
if(personId > 0)
{
// Retrieve the existing biz form item,
// and update it from the form control values
var bizFormItem = BizFormItemProvider.GetItem(personId, "customFormClassName");
bizFormItem.SetValue("FirstName", txtFirstName.Text);
bizFormItem.Update();
}
else
{
// Your code for inserting a new form item...
}
}
The Kentico way
You should really consider using the Kentico form engine for accomplishing this task. Instead of using a custom form for entering the data, use the built-in On-line form webpart.
The benefits are numerous, such as:
Ability to set the form layout through the CMS, and use alternative layouts
Automatic confirmation email to the submitter of the form, as well as notification emails to the administrators
To accomplish your task, you can customise the On-line form webpart to support loading of existing data.
In the bizform.ascx.cs file, add code to the SetupControl method:
protected void SetupControl()
{
if (StopProcessing)
{
// Existing code...
}
else
{
// Existing code...
// Get the form item ID from the query string
var personId = QueryHelper.GetInteger("personId", 0);
if(personId > 0)
{
// Get the biz form item, and set form control values
var bizFormItem = BizFormItemProvider.GetItem(personId, "customFormClassName");
if(bizFormItem != null)
{
// Set the item ID
viewBiz.ItemID = bizFormItem.ItemID;
}
}
}
}
This will automagically switch the form to Edit mode, instead of Insert mode, as soon as you set the ItemID property. Clicking the Submit button will save changes on the existing form item.
You will not need to worry about validation in your code, and inserting data will still work.
Is this a contact form that you are using Kenticos built in form application for, or is it a custom form? If it is a custom form you can create a transformation with a link that will contain the ID. If it is a biz form, you can still create a transformation in Page Types (create a new page type and select "The page type is only a container without custom fields"), then write a custom query to get the biz form data, and use a repeater to display the data with that transformation.
EDIT: I'm not looking for Facebook APIs! I'm simply using Facebook as an example. I intend to get my browser to perform actions on different websites that likely have no APIs.
Let's say I wish to create a program that will log into Facebook, lookup my friends list, visit each one of their profiles, extract the date + text of each post and write this to a file.
I have an idea how the algorithm should work. But I have absolutely no clue how to interface my code with the browser itself.
Now I'm a Java programmer, so I would very much imagine the pesudo code in Java would be to create a Browser Object then convert the current page's contents to HTML code so that the data can be parsed. I provided an example code below of what I think it ought to look like.
However is this the right way that I should be doing it? If it is, then where can I find a web browser object? Are there any parsers I can use to 'read' the content? How do I get it to execute javascript such as clicking on a 'Like' button?
Or are there other ways to do it? Is there a GUI version and then I can simply command the program to go to X/Y pixel position and click on something. Or is there a way to write the code directly inside my FireFox and run it from there?
I really have no clue how to go about doing this. Any help would be greatly appreciated! Thanks!
Browser browser = new Browser();
browser.goToUrl("http://facebook.com");
//Retrieve page in HTML format to parse
HtmlPage facebookCom = browser.toHtml();
//Set username & password
TextField username = facebookCom.getTextField("username");
TextField password = facebookCom.getTextField("password");
username.setText("user123");
password.setText("password123");
facebookCom.updateTextField("username", username);
facebookCom.updateTextField("password", password);
//Update HTML contents
browser.setHtml(facebookCom);
// Click the login button and wait for it to load
browser.getButton("login").click();
while (browser.isNotLoaded()) {
continue;
}
// Click the friends button and wait for it to load
browser.getButton("friends").click();
while (browser.isNotLoaded()) {
continue;
}
//Convert the current page (Friends List) into HTML code to parse
HtmlPage facebookFriends = browser.toHtml();
//Retrieve the data for each friend
ArrayList<XMLElement> friendList = facebookFriends.getXmlElementToArray("friend");
for (XMLElement friend : friendList) {
String id = friend.getId();
//Visit the friend's page
browser.goToUrl("http://facebook.com/" + id);
while (browser.isNotLoaded()) {
continue;
}
//Retrieve the data for each post
HtmlPage friendProfile = browser.toHtml();
ArrayList<XMLElement> friendPosts = friendProfile.getXmlElementToArray("post");
BufferedWriter writer = new BufferedWriter(new File("C:/Desktop/facebook/"+id));
//Write the date+text of every post to a text file
for (XMLElement post : friendPosts) {
String date = post.get("date");
String text = post.get("text");
String content = date + "\n" + text;
writer.append(content);
}
}
I think you are thinking about this the wrong way. You wouldn't really want to write a program to scrap the screen via the browser. It looks like you could take advantage of facebooks rest api and query for the data you are looking for. A link to get a users posts via rest api:
https://developers.facebook.com/docs/graph-api/reference/v2.6/user/feed
You could get their users id's from this endpoint:
https://developers.facebook.com/docs/graph-api/reference/friend-list/
Then plug the user ids into the first rest endpoint that was linked. Once you get your data coming back correctly via the rest api its fairly trivial to write that data out to a file.
I have an editable text web part on a page template. It has a custom HTML envelope before and after the text. How can I hide the whole thing, envelope included, if the editable text is empty?
I need to hide it because the envelope adds stylized markup that shouldn't be visible when there is no text.
Can it be done with a K# snippet on the Visible property? I'm unclear how interrogating a document's property works.
Thanks!
Try this as the "Visible" property:
{% (ViewMode != "LiveSite") || (CMSContext.CurrentDocument.editabletext != "") #%}
Change "editabletext" to whatever you have for your web part control ID.
I'm not familiar with Kentico but these solutions might help. They may not address your problem specifically but might aid in a solution.
CMSEditableImage Extension Method
I came up with a way to check this, I added an extension method for
the CMSEditableImage class that takes the CurrentPage PageInfo object
to check the value of the editable region, don't know if this is the
best way or not, but here's the code.
public static bool IsPopulated(this CMSEditableImage editableImage, PageInfo currentPage)
{
bool isPopulated = false;
string value = currentPage.EditableItems.EditableRegions[editableImage.ID.ToLower()].ToString();
if (!string.IsNullOrEmpty(value))
{
value = value.ToUpper();
isPopulated = (value == "<IMAGE><PROPERTY NAME=\"IMAGEPATH\"></PROPERTY></IMAGE>") ? false : true;
}
return isPopulated;
}

JavaScript Method
The webcontainer needs an id, example:
<h2 id="webpart-header">Headline</h2>
Then I have a small javascript function that is attached in an
external js file:
/* Hide Webcontainer via javascript if empty*/
function hideLayer(element) {
elem = document.getElementById( element );
elem.style.display = "none";
}
Now in the wep part configuration, at no data behaviour, you uncheck the checkbox and call the js function by entering following
script in the no record found text: hideLayer("webpart-header");
Whereby webpart-header the id name of your container is. You could
also have a more complex <div> structure here.

I have written a web part in C# for Sharepoint 2007 which has a single field which is validated as a required field using RequiredFieldValidator(). The web part also has some configuration fields (ones you edit by clicking on Modify Shared Web Part).
When I make changes to these fields and try to apply them, the validation of the user field kicks in and prevents the update, even though I am not submitting the form. I am only trying to submit the settings. The web part may be used in a few places on our farm, so site collection administrators need to be able to change the settings - at the moment it is not friendly enough for these users to do so.
Here is where I validate the user field:
// Validate form field - required field, and max length is 100 characters.
InputFormRequiredFieldValidator messageRequiredValidator = new InputFormRequiredFieldValidator();
messageRequiredValidator.ControlToValidate = txtMessage.ID;
messageRequiredValidator.ErrorMessage = "You must write a message to send!";
messageRequiredValidator.Display = ValidatorDisplay.Dynamic;
messageRequiredValidator.Text = "<img src=\"/_layouts/images/CNSCA16.gif\"/> You must write a message to send.";
tc.Controls.Add(messageRequiredValidator);
Here is where I define one of the configuration fields:
private string recipientEmailAddress = "sender#domain.tld";
[WebBrowsable(true),
Personalizable(true),
WebPartStorage(Storage.Shared),
WebDescription("Email address the form should be sent to"),
WebDisplayName("Recipient Email Address"),
SPWebCategoryName("Email Settings")]
public string RecipientEmailAddress
{
get { return recipientEmailAddress; }
set { recipientEmailAddress = value; }
}
This is the first web part I have written, so there may be some subtleties I am missing in how to do admin configuration and validation of user submitted fields.
Ok - I've found the key to this. You can add a validationGroup property to each validator, and to the button that causes the validation. So I changed my code to include:
messageRequiredValidator.validationGroup = "UserInput";
and a similar property to my submit button. Now when I click on Ok in the ToolPane, it doesn't validate the UserInput validation group. That only happens when I click on my Submit button.
You can dynamically disable validations on OK, Cancel buttons in ApplyChanges method:
ToolPane pane = Zone as ToolPane;
if (pane != null)
pane.Cancel.CausesValidation = false;
OR you can also check if editor pane is open and disable validation in webpart :
WebPartManager wpm = WebPartManager.GetCurrentWebPartManager(Page);
if (wpm.DisplayMode == WebPartManager.EditDisplayMode)
{
//Page is in edit mode
}
I would suggest to use the SharePoint validation control.
I have a list within Sharepoint, using a custom new form I have added a custom list form control ("New item form" for the list) and changed the SaveButton to a standard input HTML button, and added an 'onclick' event that is as follows:
onclick="javascript: {ddwrt:GenFireServerEvent('__commit;__redirect={NewFormWizard2.aspx?id=}')}"
This works as in saves the data and redirects to the NewFormWizard2.aspx?id= page.
How do I get the ID of the created item to be passed to the redirected page?
Thus once the form is completed it would redirect to NewFormWizard2.aspx?id=23
jtherkel was close, but was missing a '}' on the end of the redirect url. I used an extra concat below
<input type="button" value="Submit" name="btnSave" onclick="javascript: {ddwrt:GenFireServerEvent(concat('__commit;__redirect={lists/MyListName/DispForm.aspx?ID=',/dsQueryResponse/Rows/Row/#ID,'}'))}" />
I am not sure where the ID will exist on the page you host the Javascript from. Does it appear in the querystring or on a field on the page?
There is nothing in the request or response that will identify the item. I have had this issue when doing some web loadtesting.
I can only suggest that your create the item using the webservices as that at gives you some return xml.
This answer does not solve the "new form" issue, but it might help others with the syntax for screens that contain existing list items.
I tested this quickly in my SharePoint (MOSS 2007) environment.
onclick="javascript: {ddwrt:GenFireServerEvent(concat('__commit;__redirect={NewFormWizard2.aspx?id=',/dsQueryResponse/Rows/Row/#ID))}"
The concat syntax is an XSLT instruction that tells the processor to combine the values enclosed in single quotes. I adapted this answer from info I found here.
Loading Values in a Custom List Form
http://wssdevelopment.blogspot.com/2007_04_01_archive.html
I hope this would be helpfull:
1- In SharePoint Designer create new page, call it for example "LastItem.aspx" and place a dataview on it with a single form view for the destination list item.
2-Limit paging to just one record, set the sorting by ID and descending and filter the list to just show item which is created by [current user].
3-Now you do not need to pass any query string to this page. just replace the default "OK" button in NewForm.aspx of the list with a standard HTML input button and add this to its definition "onclick="javascript: {ddwrt:GenFireServerEvent(concat('__commit;__redirect={LastItem.aspx}". After submitting a new item to list you will be redirected to an edit view of the created item.
You can do the same for save button in LastItem.aspx to redirect to some other page after clicking on save button.
found an approach using pure javascript (JQuery) and the SPAPI code from http://darrenjohnstone.net/.
The list contains two fields, title and BodyCopy
I've thewn created a form that asks for a title and a question, both text fields, then the submit button calls the following function: (note that ServerAddress and LIST_question need to be updated to your own details).
The function then uploads the details using the SOAP service within LISTS.ASMX and using the response gets the ID of the new item and redirects the page.
var LIST_question = '{xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}';
var ServerAddress = 'http://xxx/';
function submitQuestion()
{
var title = new String($("#title").val());
var t = new String($("#question").val());
t=t.trim();
if(t=="")
return;
title=title.trim();
if(title=="")
return;
var lists = new SPAPI_Lists(ServerAddress) ;
//
var newItem = { Title : title, BodyCopy : t};
var items = lists.quickAddListItem(LIST_question, newItem);
var id=-1;
if (items.status == 200)
{
var rows = items.responseXML.getElementsByTagName('z:row');
if(rows.length ==1)
{
var r = rows[0];
var id = r.getAttribute('ows_ID');
window.location.href='DispForm.aspx?ID='+id;
}
else
{
alert("Error: No row added");
}
}
else
{
alert('There was an error: ' + items.statusText);
return;
}
}
