I have a radiobuttonlist which is a trigger for three other controls. The issue I am having is that the OnSelectedIndexChanged event is not firing the second time around. This means that the rest of the controls encompassed by the trigger doesn't update.

I need help determing why the three controls are not being updated by Ajax the second time around. Notice the boldfaced items which are the key to getting this to work.

If I remove the AJAX manager, the controls get updated successfully the second time around, but you can see the postback occurring in the browser which I ultimately don't want to see. 

Here is my html:
<code>
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="rblDataType">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="lstPatientEDLogs" />
                <telerik:AjaxUpdatedControl ControlID="pnlNoPatientInfoCounts" />
                <telerik:AjaxUpdatedControl ControlID="pnlPatientInfoCounts" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

Here is my server side code-behind: This is the code that changes the other three controls. However, when the index is changed for the radiobuttonlist, the second time around, a postback is never fired. It gets hit the first time I change the index of the radiobuttonlist, but not the second time.
<code>
protected void rblDataType_SelectedIndexChanged(Object sender, EventArgs e)
        {
            LoadDatesofSvc();
        }
</code>

I have a ASPX page with Rad grid , this grid loaded with data.

 

when a row is selected and clicked on a radTolBarButton,to edit its content . Actually it opens a Rad window (window.radopen) with all the controls in editable mode.

 

we can edit ,save and also close this window ( provided a Rad button 'Close' in a Rad tool bar )

 

My Requirement is below.

 

on edit - save - close button click

 

1.Need to close the window - (this is happening)

 

2.Need to refresh the content in the grid - from - where this rad window opend. (this is not happening)

 

 

I dont want to change Content edit procedure. This is already finalised.

 

The only thing is to refresh the grid content on Rad window close.


Please help me.

Thanks in advance

I am able to update and delete the rows from RadGrid but It gives me following exception on insert :-
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Cannot insert the value NULL into column 'Alert_Level_ID', table 'AlertEmailManagement.dbo.Alert_Level'; column does not allow nulls. INSERT fails.
The statement has been terminated.
The problem is it does insert the row in Database and I am sure that alert_level_id is not null.
eher is my code:-

I'm trying to develop custom application for SharePoint 2010 using Visual Web Part template in Visual Studio 2010, as well as converting existing standard web application (aspx) to Visual Web Part.

I would like to know if there is any difference that I should have known when starting to do it. Any difficulties or limiations?

So far, I found one difference, as stated in this blog:
http://blogs.c5insight.com/Home/tabid/40/entryid/173/SharePoint-2010-Visual-Web-Parts-Using-Script-Managers-AJAX.aspx

It is said that we must add and configure the RadAjaxManager in code-behind instead of on the aspx page like usual. Anyone please confirm for me if it is true.

Is there any other difference that I should know of?

Thanks.

When the grid is displayed in the page, everything seems fine. The links on the grid work correctly. The deletes are completed. Everything is OK except the edit command. When I click on the pencil icon, I can see the ajax icon spinning, but it never enters into edit mode. In the code I have it to show the edit as a popup window, but even if I try the inline mode, it does not work. Help...

I have a RadGrid within a RadPageView / RadMultiPage - switching pages using the RadTabStrip.  My issue is that when my RadGrid is within the RadPageView, parts of my codebehind no longer work.

The RadGrid is fully functional outside the PageView - however inside of it, it cannot access one of my Unique columns.  

The code that it cannot find is as follows:  (it cannot find the value of "bytes" because it does not see the column)


How can I rectify this situation?

Hi there,
I have RadGrid on my page with custom CommandItemTemplate(Several RadButtons). When I select a row in my grid and click on any button RadNotification is shown. But I can still select a row... How to put RadAjaxLoadingPanel over my RadGrid that will disappear after RadNotification is closed?

I want next scenario to happen:
- user select row
- click on button
- RadAjaxLoadingPanel activates & RadNotification is shown
- user close RadNotification & RadAjaxLoadingPanel is closing

p.s. Sorry for my english
 

Hi,

I am trying to write a user control with the Rad ListView to show a list of Hyperlinks which navigates to different URL.
The List of Hyperlinks are variable (show a different list in different scenarios) and also builds up different URL's.
Can someone please suggest,  how can i go about it? or is there any other control i can use to display the same. the list of hyperlinks come on a popup window.

- The datasource i am having is a List of Enum's. e.g. as List<enum> actions.
- i am not able to assign a the datasource to the Radlistview correctly, as i am not sure what will be the DataKey in my case and what property th eEval Method will evaluate??

I have also tried the object datasource but as my collection is of Type Enum i am not able to create any property in it to display it..

I need this urgently. quick help or a sample will be of great for me. we are using the latest telerik version (Q2) with 3.5

If for example I have a table in my database looking like that:
-------------------------------------------------
TEST
-------------------------------------------------
ID         int                     autoincrement PK
A          nvarchar(20)
B          nvarchar(10)    null
C          int                     null
-------------------------------------------------

So field A always require a value, but fields B and C can have nulls.
Now if I create simplest linq data source, and radgrid using that data source to select/insert/edit data in that database.
Everything is nice, except that If on edit/insert forms I leave field for B empty, in database it will input empty string instead of null. That would still be ok, I could live with it. But if I leave field for C (integer) empty, I will get an exception that the value from the field can't be converted into int32.

So my question is: how can I force radgrid to replace empty values on edit/insert form with NULL?

Thanks,

Daniel
