If anyone is having idea how to customize properties in a smartpart. I have created usercontrol and i m wrappin it in a smartpart.I want to upload my xml from Document library.
private string feedXML;
[Browsable(true),
Personalizable(true) ]
public string FeedXML
{
get
{ return feedXML; }
set
{ feedXML = value; }
}
and I am using this like
//
feedXML="\customxml.xml";
XPathDocument doc = new XPathDocument(Server.MapPath(feedXML));
but this thing is not working . When I am clicking on modify shared webpart of sharepoint page is not rendering. Any clue where I m getting wrong.
You might want to verify the result of your server.mappath statement. It will be something like C:\Inetpub...
So your code is trying to retrieve a file from the filesystem that really lives in SharePoint because you have uploaded it to a Document Library.
If you want that file you'll have to retrieve it using the SharePoint object model, have a look at the GetFileAsString method.
I agree with Denni..
Seems like Smartpart is only making it more difficult? What advantages does it have?
I make my own webpart containers for ascx controls.. very little work and all the control you need. No problems with trust settings either.
Are you sure this is correct?
feedXML="\customxml.xml";
Perhaps, what you want is:
feedXML="\\customxml.xml"; //escape the back-slash.
or
feedXML="/customxml.xml"; // use the forward-slash.
Anyway, if you just want to wrap your user control inside a Web part, you don't need the SmartPart. You can write your custom Web part yourself quite easily.

We are looking for information on how to add content to an Editable Image programatically (with the Kentico C# API). Essentially, the equivalent of this Editable Region article for an Editable Image.
Any suggestions?
Thanks,
Victor

You Sure Can
Each individual editable cms page control is stored in the document's DocumentContent field and can be accessed using an indexer field. For example:
TreeNode document = DocumentContext.CurrentDocument;
string editableImageControlId = "EditableImage1";
// get the field value
string editableImageContent = document.DocumentContent.EditableRegions[editableImageControlId];
// set it to something new
document.DocumentContent.EditableRegions[editableImageControlId] = newValue;
HOWEVER
If you look at the DocumentContent field in CMS_Document in the database you'll notice that all of the content is XML. That's because each control is serialized into XML and then nested inside this field. Thus, in this case, the value of the editableImageContent variable is an XML string:
<image>
<property name="imagepath">
~/Folder/ImageName.png
</property>
</image>
I wouldn't recommend trying to modify this directly since there's no telling if Kentico would ever change this code, or the individual control would ever change its serialization output.
But if you really must
You've got a couple of options:
1. Per #josh, you could create a new control that wraps the existing one and do some method override magic so that the control continues to do the serialization on your behalf and you just modify it after the fact. However this requires that the control is currently loading.
2. You could just hard code the beast and deal with it if it ever changes (which it likely will). Try:
// get the node from wherever you need to get the node
TreeNode document = DocumentHelper.GetDocuments().TopN(1).FirstObject;
var relativeMediaFilePath = "~/NewImage.png";
var xmlImage = string.Format("<image><property name=\"imagepath\">{0}</property></image>", relativeMediaFilePath);
var cmsControlId = "editableImage1";
if (document.DocumentContent.EditableRegions.ContainsKey(cmsControlId)) {
document.DocumentContent.EditableRegions[cmsControlId] = xmlImage;
}
else {
document.DocumentContent.EditableRegions.Add(cmsControlId, xmlImage);
}
// a little hack to get this field to be indicated as updated
document.SetValue("DocumentContent", document.DocumentContent.GetContentXml());
document.Update(true);
You could clone the editableimage webpart and then work in the prerender or change the override for the GetContent() method and add your own part of the string or do a string replace and add your code.
What is that you want to add to an Editable Image? - image path?! Not sure why you'd do that, but I'd take another direction: I'd add a field to a page type, which makes it much easier to work with through API. Having this field set up with API is should be quite easy to get it on the page... e.g. place editable image and use a macro to get field value.
Use
node.DocumentContent.EditableWebParts
and
node.DocumentContent.EditableRegions
collections to programmatically update editable content.
The best code example can be spotted at \CMS\CMSModules\Content\CMSDesk\Properties\Advanced\EditableContent\Main.aspx.cs
It's the dialog under Pages->General->Advanced->Edit regions & web parts.
We have a solution that deploys a number of lists and pages. We wan't to create links for them on the Quick Launch menu automatically when a feature is activated.
The structure could be something like this.
Customers
Active
Inactive
Sales
Quotes
Orders
And so on. The site collection admin might add another link between the "Active" and "Inactive" links. When the feature is deactivated I don't want to remove the items, but if the feature is activated again i don't want the navigation to be added again :)
Is there a built in API that you can use? I know about the SPWeb.Navigation.QuickLaunch and the SPNavigationNode(Collection) structure etc. But is there another way?
Hope you can help :)
What kind of other way would you be looking for?
public override void FeatureActivated(SPFeatureReceiverProperties properties)
{
SPWeb web = (SPWeb)properties.Feature.Parent;
// Check for an existing link to the list.
SPNavigationNode listNode = web.Navigation.GetNodeByUrl(list.DefaultViewUrl);
// No link, so create one.
if (listNode == null)
{
// Create the node.
listNode = new SPNavigationNode(list.Title, list.DefaultViewUrl);
// Add it to Quick Launch.
web.Navigation.AddToQuickLaunch(listNode, SPQuickLaunchHeading.Lists);
}
}
We have used the method above for a while and it tends to work out just fine.
If you can let me know what kind of thing you are trying to accomplish that manipulating SPWeb.Navigation wont let you do, I might be able to be of some more help
I have a custom web part where there is a text box. My custom web part also has a custom setting where user enters some values separated by commas. So on load, the UI should display the values entered in the setting (without commas though).
Is this possible with normal ascx user control, since it cannot access the sharepoint web part property at the time of creation and hence cannot display the message on load.
Need some help to solve this.
Thanx
I assumed you're probably doing something like this.
What you'll need to do is pass your web part properties to your usercontrol. You can do this by creating public properties in your usercontrol class (demonstrated in the link I give above).
Code sample from the article:
// Loads a user control
MyUserControl myUserControl = (MyUserControl)Page.LoadControl("~/_controltemplates/MyWebPart/MyUserControl.ascx");
myUserControl.Web = SPContext.Current.Web;
myUserControl.TextColor = this.TextColor;
I have not worked with webparts for sharepoint before, but need to make change to a webpart, that needs to be propagated to some 700 websites. It is a change to one of the properties of the webpart, the value needs to be changed. Is there a way to get metadata for a webpart and change it directly in the database (I assume that is where it is stored.)?
Here is the scenario: Webpart contains a comma delimited list of document types (internal type) that it should display. Now there are new doc. types that need to be added to all 700 websites. I need a way to enumerate websites, get the webpart metadata, and add these new doc types to webpart. Currently they go manually to each website, click on edit, type in new doc type, and save it.
As others have said the correct approach is to programmatically achieve this rather than edit the content database which will make your installation unsupportable. I regularly use a console application to do this in a site collection made up of sites created from a site template.
Here is an example that changes the Title property of a ListViewWebPart. Updated to include code for recursive loop. I haven't tested this but it should work.
private static void ProcessSiteCollection(string url)
{
using (SPSite siteCollection = new SPSite(url))
{
SPWeb rootWeb = siteCollection.RootWeb;
ProcessWebs(rootWeb);
}
}
private static void ProcessWebs(SPWeb parentWeb)
{
foreach (SPWeb web in parentWeb.Webs)
{
try
{
UpdateWebPart(web); // Set web part properties
ProcessWebs(web); // Recursively loop through children
}
finally
{
web.Dispose();
}
}
}
private static void UpdateWebPart(SPWeb web)
{
using (SPLimitedWebPartManager webPartManager =
web.GetLimitedWebPartManager("default.aspx", PersonalizationScope.Shared))
{
try
{
foreach (WebPart webPart in webPartManager.WebParts)
{
if (webPart.Title == "My Web Part")
{
ListViewWebPart listViewWebPart = (ListViewWebPart)webPart;
listViewWebPart.Title = "Updated Web Part";
webPartManager.SaveChanges(listViewWebPart);
web.Update();
break;
}
}
}
finally
{
webPartManager.Web.Dispose();
}
}
}
Directly accessing the sharepoint content databases is a big "no no." That's the official answer. :)
That being said, I have only ever looked in the content databases and never tried to actually change anything manually.
My suggestion, would be to modify the existing web part to modify the property based on currently set property(s). (I am assuming that some currently set property is invalid or needs to be updated based on changes to the infrastructure.) ... If this is the case, you can validate the property; making sure that current property is changed to what it needs to be, and/or making sure future property changes are valid.
Good luck!
DON'T
Seriously, do not go into the content databases and edit it. That way you are not supported anymore if anything should happen and Microsoft will not support you anymore (not until you revert the database back to an earlier version from a backup that is).
You can use the API to access webparts in your sites, here's some code that should get you started:
Enumerate page webparts
I'd like to build suitescript implementing same functionalities with standard function.
For instance on item detail page (List/WebSite/Items) clicking view button of any non inventory item, you could find out Convert To Inventory button.
Thanks to inspect that browser support, it shows some as follows
I want to build script that archive same functionalities like getNLMultiButtonByName('multibutton_convertinvt').onMainButtonClick(this);return false; but it throws error like getNLMultiButtonByName is not defined.
I want your help.
Regard
Probably you're looking for something similar
function onLoad(type, form, request){
if(type=='view') {
form.addButton('custpage_button','Custom Button',"getNLMultiButtonByName('multibutton_convertinvt').onMainButtonClick(this);return false;");
}
}
