Greetings, if I want to augment the functionality of one of the Telerik javascript "classes", is there a proper way to override a function such that my change will be applied after the initial Telerik js declarations/file references, but before the $create() function calls which use the classes that are being modified?

For instance, I'd like to tweak the "initialize" function in the WebServiceRenderingManager class. So at some point after WebServiceRenderingManager is declared by the Telerik js script I want to update the prototype for it: 

Is there a standard way/place to include my code above so that it will run after the initial WebServiceRenderingManager prototype is defined, but before the client-side code executes that initializes the control instances ($create(Telerik.Web.UI.RadScheduler, {...});)? Is there a best practice for this? 

Btw, I only need to do this for a particular aspx page, not globally for my entire site.

Thanks in advance!

    End Sub

with RadGrid1 how would it be?

sorry my english

Dear Telerik team I request you to please help me in resolving below issue as I am not much familiar with Telerik and Sharepoint environment. I posted my issue in other forums too but did not got any solution.

There is a "RadGrid" inside which there is a "RadComboBox" and a "asp:Button" next to it.
This RadGrid is NOT ​​inside "RadAjaxPanel" due to some reason.
When user key-in any text in RadComboBox and click on Button, only then the searching (related to key-in text) is started in RadComboBox and displayed in a DropDownList.

Now, when user type/key-in any text in RadComboBox and click on Button, then the related data binds to DropDownList of RadcomboBox but the DropDownList appears to stick at the bottom of the page and the whole page scroll shifts to half of the page.
and When I click outside of DropDownList then page becomes normal & DropDownList get closed. 

Please let me know why is this happening when I DONOT put RadGrid inside RadAjaxPanel ?

Below is the code I am using so far:

<script>
//disable opening of RadCombo dropdown when click on left image of dropdown
function OnClientDropDownOpening(sender, args) {
if (sender.get_items().get_count() == 0 || sender.get_text() == "") {
    args.set_cancel(true);
    }
}
//hide RadCombo dropdown If the text area is blank
function OnClientItemsRequested(sender, eventArgs) {
if (sender.get_items().get_count() < 1 || sender.get_text() == "")
    sender.hideDropDown();
}
</script>​

 Please note that I am using Sharepoint in my application.

I tried all possible ways to solve this issue like: 

1.  MaintainScrollPositionOnPostback="true"

2. Setting the RadGrid scroll position in ClientSettings tag

3. used few javascript code 

but nothing worked in my scenario. Please somebody help me, I am facing this issue since long and I have to complete it at the soonest.

Thanks in advance.

Hi All,

Let me start off by saying I am a noob when it comes to using asp.net and telerik. With that being said I am having an issue updating the headers of the rad grid. When I run the application in Visual Studio the headers are correct, however when I build the solution and run the application on the internet the headers still reflect the old text (before the text change).The  application in question was built by someone else using asp.net, c#, javascript, ajax, etc. I am pretty sure the version of telerik used originally is much older than the version I am using today which is the most current version as of 9/15/15 . I should also mention there are two versions of the application one being used now by employees and one I am working on a development sever. The header text that should be changed should be both the Approval and Status text.

I added two images below to show you what the app looks like in visual studio vs what it looks when run on the internet.

Hi community,

I have a several RadDatePicker and one RadMonthYearPicker control on a simple page.

I was trying to hide some of them by condition through client side event only, so I write a handler and try to use client object methods to hide them.

 My handler looks like:

Both alert message pop up without any javascripts error, but none of the control is hidden...

This is my first trial, then I try to work around with get_textBox() and hide the text box rendered.

Now the DatePicker is hidden but not the MonthYearPicker...

What have I do wrong and how can I achieve such easy tasks?

I am using Telerik Ajax 2012.1.411, and my browser is Chrome & IE8+

Thanks!

I can find no way to properly format my source code samples here on this forum. The painbrush icon (Format Code Block) simply doesn't work, and never has. Begging everyone's pardon, could you please see my question on Stack, which formats code samples nicely. If anyone can tell me how to properly format my code blocks here on this forum, I am happy to learn.

Thanks very much.​

I have a RadGrid with that works correctly outside of the RadPanelBar.  When I put it inside of a RadPanelBar the OnCheckedChanged="ToggleRowSelection" does not fire.  Does "protected void ToggleRowSelection(object sender, EventArgs e)" need to be defined differently?  It looks like the auto post back works because the check mark disappears.  If I remove ToggleRowSelection in the c# section I get a compile error indicating that there is no definition for ToggleRowSelection so I think it is all correct. 

 Thanks,

 Scott

 Grid is not refreshed after ItemCommand event

Protected Sub Parts_ItemCommand(sender As Object, e As GridCommandEventArgs) Handles Parts.ItemCommand
If e.CommandName = "DeleteInventory" Then
Dim filename As String = _uploadSystemPath & "tree.xml"
Dim XMLDoc As XDocument = XDocument.Load(_uploadSystemPath & "tree.xml")
XMLDoc.Root.Elements("Node")(e.Item.ItemIndex).Remove()
XMLDoc.Save(filename)
XMLBookBuilderSource.DataFile = _uploadSystemPath & "tree.xml"
Parts.DataSource = XMLBookBuilderSource
Parts.DataBind()
End If
End Sub

UI for ASP.NET AJAX version: 2015.1.225

I'm trying to grab information from the radgrid when the user selects a row.  The Javascript function fires as expected, but I can't seem to get the right syntax to grab the cell information.

    <script type="text/javascript">
        function launchDetails(sender, eventArgs) {

        }
    </script>

If I use 'sender.MasterTableView.getColumnByUniqueName("caseName");' I get the column information as expected.
If I use 'parseInt(eventArgs.get_itemIndexHierarchical());' I get the selected row index as expected.

If I use 'sender.MasterTableView.getCellByColumnUniqueName(parseInt(eventArgs.get_itemIndexHierarchical()),"caseName");' I get the following error:
'Uncaught TypeError: a.get_element is not a function(…)' at 'Telerik.Web.UI.GridTableView.getCellByColumnUniqueName'

I've also tried this line of code without the 'parseInt', but obtain the same results.  How can I grab the "caseName" at the designated clicked row?
