Material

Why, when I use Material as the base for a theme - do I only have 2 options? Nothing under primitives - so I can't (for example) give RadMenu a background of other than white.

Am I doing something wrong?

usercontrol in nestedviewTemplate

hi all ,

i have radgrid on page with nestedviewTemplate , in nested view template i call user control (.ascx)

page size is 10 for mastertable

in user control i have one radgrid . when i load page it goes in load event of user control for 10 times (page size of master table)

and load the entire grid on user control 10 times .

it takes too long time ,so for any postback (syn/asyn) pointer go in user controls load method .

i dont want this scenario ,instead i want when user clicks on expand button only that time it should call the usercontrol for only taht record and fetch same data for record only instead of binding all data every time

how should i go further ...looking for helping hands :) thnx in advance

RadComboBox ClientState form data is empty on form submit

Hi, I have a simple ASPX page with a RadComboBox. I have noticed that the "ClientState" form data doesn't get added to the request when the form submits unless I have opened the combobox and made a selection. Is there any way to get ClientState to populate without making the user select one of the list items--say a default option?

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

Display Session timeout Notification

Dear Telerik Team,

We would like to use rad notification session timeout feature in my code but we have different project scenario.

We have master page in project but Form tag is inside content page so we are not able to add notification control in master page.

We don't want to add rad notification on each page.

We have created a dynamic control on page load but getting error on continue session button.

ComboBox checkitems as asp control parameter

Is there a way to specify a property from the combo box setup with check items to be passed to a control parameter property?

<asp:ControlParameter ControlID="cmbProviderSort" DbType="Int32" ConvertEmptyStringToNull="true" DefaultValue="-1" PropertyName="SelectedValue" Name="a" />

PropertyName is set as SelectedValue which will only work with a non checkbox combo box. What is the best approach to be able to send in all checked items into the asp:ControlParameter.

I have to use the DataSource setup in this way and cannot do it in the code behind. Thanks

Menu re-opens after exporting from a grid

I have a page with a RadGrid. Several functions for the grid are in a RadMenu. Several of the functions trigger a JavaScript function to open dialogs, windows, and whatnot, while another menu item does a postback to export the contents of the grid to a .csv file. Everything works fine, with the exception of the export. The menu works properly up to the point where the postback completes and the .csv begins downloading. At that point, the menu re-opens with the Export item highlighted. Is there any way to keep the menu from re-opening after the export is complete?

Here's my menu:

<telerik:RadMenu ID="RadMenu1" runat="server"

ExpandDelay="0"

CollapseDelay="0"

ExpandAnimation-Type="None"

CollapseAnimation-Type="None"

ShowToggleHandle="true"

OnItemClick="RadMenu1_ItemClick"

OnClientItemClicking="OnClientItemClicking"

ClickToOpen="true"

Skin="Windows7"

>

<Items>

<telerik:RadMenuItem Text="Menu" PostBack="false">

<Items>

<telerik:RadMenuItem Text="Save..." />

<telerik:RadMenuItem Text="Save As..." Enabled="false" Visible="false" />

<telerik:RadMenuItem Text="Delete" Enabled="false"/>

<telerik:RadMenuItem Text="|" runat="server" IsSeparator="True" />

<telerik:RadMenuItem Text="Schedule..." />

<telerik:RadMenuItem Text="Export" />

<telerik:RadMenuItem Text="Print" />

<telerik:RadMenuItem Text="|" runat="server" IsSeparator="True" />

<telerik:RadMenuItem Text="Reset Grid" />

</Items>

</telerik:RadMenuItem>

</Items>

</telerik:RadMenu>

Here's the JavaScript that sits behind the menu:

function OnClientItemClicking(sender , args) {

var itemText = args.get_item().get_text();

switch(itemText) {

case "Save...":
