I am trying to access a radsplitter control via client-side scripting.

The radsplitter i am trying to reference is nested inside of another radsplitter/radpane.

Here is an example of how i access the splitter:

var splitter = $find("<%= innerSplitter.ClientID %>");

 

<

telerik:RadSplitter ID="outterSplitter" runat="server" Orientation="horizontal">
<telerik:RadPane ID="pane1" runat="server" >
<telerik:RadSplitter ID="innerSplitter" runat="server" VisibleDuringInit="False">
<telerik:RadPane ID="pane2" runat="server" Scrolling="none"  OnClientResized="afterResize">
left pane of the splitter
</telerik:RadPane>
right pane of the splitter
<telerik:RadSplitBar ID="splitbar1" runat="server" />
<telerik:RadPane ID="pane3" runat="server" OnClientResized="afterResize2"></telerik:RadPane>
</telerik:RadSplitter>
</telerik:RadPane>
<telerik:RadSplitBar ID="splitbar2" runat="server" CollapseMode="None"/>
<telerik:RadPane ID="pane4" runat="server" height="20px" Locked ="true" >
bottom pane of the splitter
</telerik:RadPane>
</telerik:RadSplitter> 


Everything is named appropriately, etc.


The value of splitter is always null.

 

Hi,

I've posted this in another forum on here by accident, I think I've put this into the correct forum now.

I want to know if it is possible to update a label that is wrapped in a RadAjaxPanel using code behind?  I.e.:

ASP.NET:

<

telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" height="200px" width="300px"> <asp:Label ID="Connections" runat="server" Text="0"></asp:Label> </telerik:RadAjaxPanel>

Code behind ( C# code ):

Connections.text = "100";

I can't get this to work unless I do a postback which is obviously not what I want.
I know this will probably work if I have a timer event and do it in that, but don't want to use one.

Any help is much appreciated.

Regards,
Steve

Hi,

I am doing live grid update. It works fine if there is only one page.
But if I am on page 2 and webservice is called then e.NewPageIndex gets -1, and that throws error.

If I try to use viewstate to reset CurrentPageIndex value then I get error "The specified value cannot be set on CurrentPageIndex" in "RaisePostBackEvent"
on below statement
MyBase.RaisePostBackEvent(source, eventArgument)

Any input please.

Thanks & Regards,

Text='<%# DateTime.Now.ToString() %>' but not working

My 3.5 controls are showing up in 3.5 projects.  

I'm trying to add a toolbox for RadControls for ASPNET AJAX to my 2.0 project in VS2008.  I followed the instructions here:

http://www.telerik.com/help/aspnet-ajax/installaddingtovs2008.html

I get this error:

---------------------------
Microsoft Visual Studio
---------------------------
There was an error loading types from assembly 'D:\Program Files\Telerik\RadControls for ASPNET AJAX Q2 2008\Bin\Telerik.Web.UI.dll'

'Could not load file or assembly 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.'

I would like to add functionality to export certain custom data from an ajaxified page.  On the user clicking a button, the logic would normally look something like:

Response.Clear()
Response.ContentType = "application/vnd.ms-excel"
Response.AddHeader("Content-Disposition", "attachment; filename="Export.xls")
....
Response.Flush()
Response.Close()

I would like to implement the same functionality with RadAjaxManager, and have Excel open in a new window leaving the original window open and unchanged.  I know I cannot use the Response object in this way with RadAjax.  Is there an alternative to doing this without posting back?

 

Using  radgrid for 2008, 2, 826, 20  .net 2.0

I have a grid controlled by a dropdown.  Most items in the dropdown cause a single row to be displayed.  1 item in the dropdown causes all row's to be displayed.

If i choose the option to show all rows first, then with paging move to page 2, then change the dropdown to show a single row, the grid reports that "No records could be found", I assume because it is insisting to show only page 2 of 1.  Same sequence without moving to page 2 results are as expected so it is not a data issue.

Is there a way for me to force the page back to page 1 on selectedindexchanged event?  Currently the event only does a grid.rebind.

I am using a .NeedDataSource event in the code behind.  Grid in the .aspx is defined as below.

It doesn't seem to matter what I set the RadTreeView Height to, when the tree view is in a RadWindow that is displayed in response to a button event the tree view is always the default height ????

Anyone else see this behavior or otherwise have a solution for me.

Thanks,
TK
