I have a drop down list inside the radgrid and the button outside the radgrid. Also I have asp.net update panel for making the cursor busy while processing. when I changed the drop down value in less than 2 drop down everything works fine and it update the gradgrid after processing complete.  But when I change the 3 or more dropdown list value, I am getting error message like

 Unhandled exception at line 15, column 16485 in http://localhost:85124/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=RadScriptManager1_TSM&compress=1&_TSM_CombinedScriptsJavaScript runtime error: ....

Sys.WebForms.PageRequestManagerTimeoutException: The server request timed out.   etc   kind of error message. ​

Can you please provide suggestion how can I fixed this issue?

Thanks in advance

Hello,

I was running into problems with too much text being displayed in certain columns within my grid. In ItemDataBound() I used the text.substring method (C#) to shorten the data to appropriate length. This was done similar to the directions provided in this post:

 http://www.telerik.com/forums/limit-amount-of-text-shown-in-data-column

Meanwhile I have implemented the Grid Excel export functionality. Unfortunately, my data within the Excel export is incomplete because it is being shortened to fit my columns. 

How can I limit the amount of text shown in a column, but still export all data when using the Excel export functionality?

Thanks,
Matt

Hello guys,

1 - How to maintain the scroll position when expand a node in the RadDropDownTree? when the tree has a lot of parents node ?

2 - How to maintain the scroll position when re-open the tree list when has a node selected? In this case are allowed only one select items

Hello

Any hints on how to solve this in javascript ?

 I need radcombo to show normal selecttext list when open, but a different selecttext when closed.

 ex. Items a,b,c    

  when "b" selected and radcombo closes i should show "mytext"

any clues would be appreciated.

I have a radPanelBar that is is bound to an SqlDataSource. Normally I would use findcontrol in the OnItemDataBound event to access the controls in the template as follows:

But apparently ItemDataBound is too early in the cycle to access controls as findcontrol always returns Nothing.

I can access the controls in the ItemCreated event, but how do I access the DataItems there?

I want to do something like:

How do I access the DataItems?

Thanks

Hi, 

I have an AutoGenerate delete link in my aspx page.  

AutoGenerateDeleteColumn="True"

Currently, when the use clicks on the delete button, the record is deleted without any warning or confirmation. How can I ask the user if they are sure of the deleting the record or not? After confirmation only the record should be deleted. I am currently deleting the records from the DeleteCommand event in the code behind. 

I saw a thread about the same issue, but I am not able to understand, how can I set the ConfirmText property for the AutoGenerateDeleteColumn. Can anyone help me with addition of this feature without requiring to change my current set up. Thanks..

Hi there,

I am trying to implement getting data for the Scheduler (Q1 2014) via a Web Service.

I have followed the instructions and created a new class derived from SchedulerInfo.

My aspx contains the following: <telerik:RadScheduler ID="RadScheduler1" runat="server" OnAppointmentsPopulating="RadScheduler1_AppointmentsPopulating" OnResourcesPopulating="RadScheduler1_ResourcesPopulating">
            <WebServiceSettings Path="SchedulerWebService.asmx" ResourcePopulationMode="ServerSide" />
  
        </telerik:RadScheduler>

I can add custom values to this in the server side code using

protected void RadScheduler1_ResourcesPopulating(object sender, Telerik.Web.UI.ResourcesPopulatingEventArgs e)

 so I seem to be on the right course.

However, when I try to do the same for the AppointmentsPopulating event, this is never fired.

Have I done something obviously wrong?

Hi All

 I have a question that might be easy to answer, but since I'm new to Telerik, I can't figure out the answer

my situation is like this

I have a RADGRID on a Webform , I changed the Columns backcolor at design time

 and i have to change some cells backcolor programatically according to certain condition 'i.e I change the color of a cell if it has negative value '

 my Problem is

 when i export the RADGRID to Excel with the EXPORT To Excel button of the Commanditem,

i get an excel sheet with the same colors for the columns as they are in the RADGRID

but the programatically changed backcolor for the negative cells are not exported

 it have no backcolor in the produced Excel sheet

 Although I welcome any solution whether C# or VB , I'll be grateful if you provide a solution in VB.NET

 Your Prompt response is highly appreciated

Regards
