I am simulating the click of a treview node in Javascript using

get_linkElement().click()

This works perfect in IE8, but Firefox 4.0 and Chrome cannot find the click() function and raises an error.

Any ideas on how I can work around this?

Thanks

Hi everybody,

i am customizing the AlertTemplate of my RadWindowManager.
I have some trouble with the button inside the template.
While using an asp:button without any problems i always get an error when i change the asp:button with a radbutton-control.
The errormessage says:

"Page cannot be null. Please ensure that this operation is being performed in the context of an ASP.NET request. "

In detail:

"[InvalidOperationException: Page cannot be null. Please ensure that this operation is being performed in the context of an ASP.NET request.]

Is this behavior by design? Can i use radbutton in the templates of RadWindowManager?

Hello,

Hi,

I am evaluating Telerik Grid for a commercial application, and have a need to do some custom formatting on some cells. The scenario is that one of the columns would have data such as "John Smith - 1234" and I would like to display only "John Smith". The caveat is that if the user chooses to group by the column, I need the grouping to be done according to "John Smith - 1234".

In situations where there is a "John Smith - 1234" and a "John Smith - 5678", they would both display as "John Smith" in the grid, but if I group by the column they would be separate groups.

Is that supported by Telerik Grid? I could not find relevant documentation or examples.

Thank you,
Nicolas

Folks,

Environment: RadControls for ajax 2011 v1 with VStudio 2010. I am using below link as a prototype.

http://demos.telerik.com/aspnet-ajax/grid/examples/programming/detailtabledatabind/defaultcs.aspx

I know there is a Telerik tutorial to hide the (expand/collapse) if no child rows. But my intention is to hide the expand/collapse if no child rows or Customer name starts with 'AN' or 'BL' in GridDataitem.

Thanks

Hello,

 I have a grid. In which one of the column header I have added image in ItemDataBound event.

I observed that the image is added next to text.

Is it possible to change the location of image within column header ?

Also I wish to have more control on the space and alignment of the image ? 

Hi,

   I am using RadGrid ,an d i have given ClientselectColumn for multiselect.
From the server side am using following code

string

 

script = string.Empty;

 

 

script = script +

"selected = new Array();";

 

 

 

foreach (int id in lstselectedIDS)

 

 

{

 

script = script +

"selected.push(\"" + id + "\");";

 

 

}

 

script +=

"SetSelectedRowCount();";

 

 

 

base.AddStartupScript(script);

from the client side am taking the elements in the selected array and making the selection in Rowcreated event  like this

 

 

function

 

Grid_RowCreated(sender, args) {

 

 

 

 

var _Id = args.getDataKeyValue(sender.get_masterTableView().get_name());

 

 

 

 

if (selected.contains(_Id)) {

 

 

args.get_gridDataItem().set_selected(

 

true);

 

 

}
}

Because of this when ever i click on Check box for deselecting it is happening correctly. But if i click again for selecting it it is not happening properly. I need click checkbox 2 times for making a selection.

This is happening only for the selected rows.

If i use server side selection in ItemdataBoud Event, am not getting this problem.
Like
e.Item.Selected=true;
But i need to use the former one

And also am facing this problem in  many screens,please help me by giving the solution as soon as possible.


Thanks,
John

In the legacy TreeView, you could set the NavigateUrl and Target properties on a Node.  When used in conjunction with the RadSplitter, you could load content into a specific RadPane by using these settings on a Node  This appears to be broken in the just-released Q3 version.

For example, in this example, when you click on one of the TreeViewNodes, the entire page gets replaced by the NavigateURL setting.  You would expect that the content gets directed into the Content pane.

<

telerik:RadSplitter ID="RadSplitter1" runat="server" Orientation="Vertical" Width="700" Height="500">

<telerik:RadPane ID="Tree" runat="server" Width="30%">

<telerik:RadTreeView ID="RadTreeView1" runat="server">

<Nodes>

<telerik:RadTreeNode runat="server" Target="Content" Text="MSDN" NavigateUrl="http://msdn.microsoft.com"></telerik:RadTreeNode>

<telerik:RadTreeNode runat="server" NavigateUrl="http://www.google.com" Target="Content"

Text="Google">

</telerik:RadTreeNode>

</Nodes>

</telerik:RadTreeView>

</telerik:RadPane>

<telerik:RadSplitBar runat="server" />

<telerik:RadPane ID="Content" runat="server" ContentUrl="about:blank" Width="70%">

</telerik:RadPane>

</telerik:RadSplitter>

I'll open a case.
