I need your suggestions for my problem area. I am working with SharePoint 2010. My requirement is to create a single web part that has only one DropDown List. Say DropDown List for continents. Now I want to use the same web part more than once on my page to have a cascading effect e.g Continents|Countries|States|Cities|so on.
So my single web part can accept and provide connections.
Though I have been able to create a both provider and consumer web part but I am strucked with post backs. Ever time a DropDown's value is changed all the other DropDowns get bound again and lost the values.
Please suggest me some options.
Thanks a lot.
Kind Regards
Vivek
Try the answer for a similar question here. Check if your dropdowns are rebound on postback. If so make them bound only once.
I would suggest to use the Querystrings to store the dropdown state. This would also help you in creating Deep Url's. We did the same thing on the sharepoint features page here : http://sharepoint.microsoft.com/en-us/product/Pages/Features.aspx
Check if ViewState of dropdowns is enabled.
You can also use cascade dropdown based on Client Object Model.
Take a look at this utility i just released : http://sylvainlancien.blogspot.fr/2013/11/slnspcascadingdropdown-jquery-cascade.html

Good day to you. I am newbie in SharePoint 2013 so please bear with me. I have created around 15 lists in my website each containing same columns but different data (they differ semantically).
I am aware that we can change the default view, edit and display form for each list by creating new form in SharePoint Designer 2013. This seems like a very bad approach as far as the maintenance is concerned. I know my lists are exactly the same so why do I have to create same 15 display forms for each of the lists?
Is there a way to create one custom Display form (may be in a central location, i don't know i am just thinking :P ) for all the lists? Is there a way to tell a list to use a specific display form? Any help will be highly appreciated. Thanks.
If i understand your question correctly, you have 15 lists with same set of columns. You want to change the display/look of the form. All 15 lists should have same look and feel right!! If yes, then why don't you try with some html, javascript solution. Since you are in sharepoint 2013, javascript support for solutions is very good like rest queries. You can use SPServices also.
If you want to to add data to the list whenever you click on the "New Item" link in the list then hijack this link such that it should navigate to your custom form. Pass your list name as query parameter. Whenever user is saving the form, get the list name from the query parameter and save the data to that list.
There could be another ways also to achieve the solution with html and javascript.

Sam I think you can create a custom content type and create custom display form for your content type. Enable the content type in each of your lists so automatically this customized form would be available.
The advantage of this approach is that suppose if you need one more list after some time you can just add this content type and your form would be available into the new list as well.
The approach is explained in the link below.

Just wanted to write the solution which I implemented as it might help others as well. (Thanks Hiren and Mihir for your valuable inputs)
I had 15 lists and I was showing the data to the user using content search web part with custom display template. All of the lists were using the same display template so I made a new page just to show the item details. In the display template I pointed the item URL (i hijacked the list name and the current item id) to my new page and displayed the item. Let me know if anyone is interested in the whole solution or further elaboration is required.
I have a basic knockoutjs project loading data from a SharePoint 2013 list scenario. Getting data and displaying data is easy, the problem that I'm running into is on the edit mode displaying the proper control. Everything should not be a textbox. This means the people picker control to dropdownmenus to calendar controls.
MSFT has some pretty good documentation on using the client side people picker control here"http://msdn.microsoft.com/en-us/library/office/jj713593.aspx
The problem that I have is calling this control inside my viewmodel.
Setting the value of the control doesn't look difficult courtesy of this blog post: http://www.sharepointcolumn.com/sp2013-setting-people-picker-value-in-newform-aspx/
I attempted to looking into computed values, but that doesn't seem to work. Does anyone have a blog post that I skipped over? The closest related post that I can find: http://yetanothersharepointblog.wordpress.com/2012/12/11/working-with-sharepoint-lookup-columns-in-knockout-js/
Lastly since it seems that I'm the only one doing this, does anyone think that I should not be reinventing the wheel with my forms and should just link each item to the appropriate SharePoint list item in edit or display view? I suppose that would be easier.
From a SharePoint Professional to another, I would highly recommend you to do that.
Just redirect the user to the item edit/display item page an let SharePoint take the leash of how to handle UI form elements.
Because, assume that you implement your custom form, what if the user decides to add one more site column to the list? Will you update your code to support another field?
From my personal experience with the beast I've come to the conclusion that structural implementation over already existent functionality tends to go wrong.
Also, if you have some kind of listing of items custom made and you want to provide editing, try to do something opening a pretty SP.UI.ModalDialog, its elegant and you use the sharepoint to do the work for you.
But it's just an advise.
I have a wss 3.0 install which needs an "anonymous" discussion board. I can modify the view so no usernames are displayed, however when I click on "reply", the message I'm replying to shows up in the rich text box with the username of the previous poster.
Is there a way to remove that username? or Remove the previous posted text altogether? I've found the schema.xml file with lots of relevant info under the ..12\TEMPLATE\FEATURES\DiscussionsList\Discuss folder, but not sure if this is the easiest way to adjust this setting.
Any comments appreciated.
Best practice says that you should always create a custom list definition instead of trying to modify the OOB assets.
The easiest way to do this is take a copy of the 12\TEMPLATE\FEATURES\DiscussionsList\Discuss folder, modify the feature Ids and names so that its unique. Then your free to change the schema render template (i.e view schema) and modify the edit and display forms.
If you need to modfify the actual entry form you may consider a custom control template : http://msdn.microsoft.com/en-us/library/aa543922.aspx

Agrothe,
I have a similar requirement (hide or mask the author inside the reply thread.). What exactly inside of schema.xml do you think will allow you to do accomplish that?
Not sure if the list forms are exposed to xslt. If so, then perhaps this is another approach.
FWIW, the other solutions I have investigated:
(1) A custom event handler. Unfortunately, I can't pinpoint which event fires when someone click reply.
(2) Anonymous blog comments (http://blogs.msdn.com/sharepoint/archive/2007/08/06/anonymous-comment-feature-for-sharepoint-blog-now-available-on-codeplex.aspx).
(3) the other thing I am considering, is to introduce a global anonymous active directory login, which users can use to post anonymously. Not ideal, but for the amount of time I have spent researching a solution, might be my last hope.
This should be a really really simple thing, but for some reason it is just eluding me.
I want a Sharepoint page which will have a drop down list that is tied to a database lookup table.
When an item is selected and they click a GO button, I want it to update a gridview that is also on the page.
I'm looking for a simple how to - while assuming I'm a sharepoint idiot. BTW, I am using the Microsoft Office Sharepoint Designer.
Thanks,
Edit:
My need is actually very simple. I want to filter the results of a query using a drop down list. This used to be called a master - detail relationship.
For example, my regular data has school name, application name, and how long the application was running. Because there could be a hundred applications per school and there are 60+ schools, I only want to show one schools information at a time.
So, I want to put a drop down list at the top of the screen which contains the list of schools. When one is selected, the gridview should be updated to reflect the new schools information.
Chris.
I currently use a drop down tied to one sharepoint list to filter a dataview of another sharepoint List.
The instructions are here:
http://blogs.msdn.com/sharepointdesigner/archive/2007/03/05/asp-net-controls-filter-the-data-view.aspx
I'm not exactly sure of the specific needs here, but it seems that you are trying to stretch a bit beyond what Sharepoint Designer is well suited to. To look up data, you do have access via the dataview web part, which is here:
http://office.microsoft.com/en-us/sharepointdesigner/HA100948041033.aspx
However your filtering needs may prevent you from using this. If you want to do it .net without knowing too much about MOSS, you can use the "son of smartpart" (google it) which allows you to host standard .net user controls in webparts.
Hope this helps!
We deployed a feature that installs a custom site column named "Classification." It is a Choice column type. Now, we need to change the choices. We can update the XML in the feature easily enough, but it doesn't affect any of the lists already used the existing site column; they still see the old choices.
Is there any way to send a refresh signal or something to the lists that use our Classification site column feature to have those lists use the updated choices?
I think the only way to archive this is by iterating each list that uses the column and change the XML there as the column within a list has no reference to the original column any more.
Flo has a point, and I have previously been working with this issue and have made a blog post that might help you out somewhat. Have a look:
http://johanleino.wordpress.com/2009/08/11/propagating-updates-to-content-types/
SharePoint can do this.. Don't change your feature but modify the created site column in each site collection through the web UI. Changes made this way will propagate.
(I hope you don't have 10.000 site collections ;)
