I have a aspx web form which contain RadWindow manager with multiple windows in it. When I open up window via the radwindow manager it seems it won't "affect" the session timer within the "parnet" aspx web form. How can I make it so that when there is a ajax call or a page refresh, within the radwindow, it will refresh the session timer of the "parent" web form?

The issue is that the user think that they are still using the web page, but yet they keep getting kick off when session expires on the "parent" web form.

Thank you!

SelectedIndexChanged not firing when selection changed with the keyboard

I have seen a couple of postings that seem to be related to this issue, but with no definitive answer.

I have a RadComboBox (in ASP.NET) with runat=server and AutoPostBack=true. I have a handler for OnSelectedIndexChanged.

The handler fires when the user selects an item with the mouse. The handler doesn't fire when the focus is on the control and the user changes the selection using the keyboard (arrow up/down).

The handler will execute in this case when the control loses focus, but that's not the desired behavior. We have sections of the page that will be shown/hidden based on the user's selection, so the user expects those changes to happen as their selection changes.

What's the official position on how to handle this?

My version of Telerik.Web.UI.dll is 2013.1.417.35.

Thanks,

David Cater

how to prevent a radwindow from opening twice from the same link

I have a page that has links to pop up help documents in a radwindow. The issue I want to resolve is if a user clicks a link more then one time I don't want multiple radwindows with the same help information. Is there a way to prevent the same link from opening multiple times?

Here is the code i'm using to load the radwindow

<script type="text/javascript">
    function GetRadWindow() {
      var oWindow = null; if (window.radWindow)
        oWindow = window.radWindow; else if (window.frameElement.radWindow)
          oWindow = window.frameElement.radWindow; return oWindow;
    }

    function radWin(myurl)
    {
      var oManager = GetRadWindow().get_windowManager();
      setTimeout(function () {
        oManager.open(myurl);
      }, 0);
    }
</script>

Part of datagrid
<ItemTemplate>
   <%# DataBinder.Eval(Container.DataItem,"Path")%><a href="javascript:radWin('../temp.aspx?ID=<%# DataBinder.Eval(Container.DataItem,"ID")%>')"><img src='../Images/Info.gif' border=0 alt="" /></a>
</ItemTemplate>

Thank you

Keyboard Enter to select

Hello

Im trying to fire a simple onclientnodeclicking event on my treeview via keyboard (hitting enter).

But I find that upon pressing Enter on the node, besides firing the onclientnodeclicking event, also fires a postback on a Button1 situated on the same page.
How do I prevent this?

Using the mouseClick on the treenode works as expected, without Button1 postback.

Simple example to illustrate:

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script type="text/javascript">

function NodeClick(sender, eventArgs) {
var node = eventArgs.get_node();
alert(node.get_text());
// eventArgs.set_cancel(true);
}

</script>

</head>

<body>
<form id="form1" runat="server">
<div>
<telerik:RadScriptManager ID="RadScriptManager1" runat="server">
</telerik:RadScriptManager>
<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" TabIndex="1" />
<br /><br />
<telerik:RadTreeView ID="RadTreeView1" Runat="server" Width="200px" Height="200px" TabIndex="2"
onclientnodeclicking="NodeClick" ResolvedRenderMode="Classic">
<Nodes>
<telerik:RadTreeNode runat="server" PostBack="False" Text="Root RadTreeNode1">
</telerik:RadTreeNode>
<telerik:RadTreeNode runat="server" PostBack="False" Text="Root RadTreeNode2">
</telerik:RadTreeNode>
<telerik:RadTreeNode runat="server" PostBack="False" Text="Root RadTreeNode3">
</telerik:RadTreeNode>
</Nodes>
</telerik:RadTreeView>

</div>
</form>
</body>
</html>

Column Title with Checklist Filtering

Hello,

My customers would like to combine the column titles with checklist filtering. They would like to eliminate the textbox and display only the checklist button next to the column title as shown in the attached image. I realize that Radgrid does not have any built in ability to do this, but is there a way to customize it using code behind and/or client side scripting? If so, can you provide, or point me to an existing example?

Thanks,
~Sonny

DNN and design support

Hello,

I'm developing for DotNetNuke and would like design support, however the needed dll's for this feature are not present in a DNN install. My account will not allow me to download the version of the Telerik design dll I need which is 2013.2.717.40.

Upgrading the telerik controls in dnn to the version I do have results in some incompatibilities.

Any way of obtaining the necessary dll's for design support?

Can multiple RadPageLayout controls be used on a form?

It may sound like a ridiculous question, but here is my thought. I need to convert a very complicated completely dynamic site to responsive design. It might be a hard sell to ask the team leader if i can start the shell from scratch with RadPageLayout, BUT if i could cut my teeth by using RadPageLayout in some of the larger sections, I'll bet i could sell the concept of the whole thing. For specifics, if i had three large divs, going vertically down the page, could i make the 2nd and 3rd ones each contain there own unique RadPageLayout control?

RadGrid filtered by RadCombobox not filtering

I have a Combobox and grid in a widget. The grid needs to be filtered as the selection in the combobox changes. Currently when the selection changes, the grid reloads, but always displays the same data. Any ideas how to fix this? Or even debug it?
