I have a NestedViewTemplate which will contain several labels and another RadGrid. Because it's expensive to get the data for the labels and nested grid, I'd like to do this only when the NestedViewTemplate is visible.

I set the HierarchyLoadMode to ServerOnDemand and registered for the ItemDataBoundEvent. In the ItemDataBound event, I check the ItemType, and if it's NestedView, I do my expensive data lookups and bind to the labels/grid.

This works great, except that the NestedView items are being databound not when I expand the item in the grid, but instead when the grid is initially databound.

What am I doing wrong?

How To Prevent Double-Clicking Of Any Toolbar Button

I need to be able to prevent users from double-clicking on a toolbar button or very quickly click on two toolbar buttons. Or better yet, have the whole toolbar disabled after single-clicking on a toolbar button.

This is just to prevent any intended function to be run more than once or to prevent any unintended function to be executed.

Thanks for any help.

Button Icon Skin

I have the skin for my project set in the web.config like so:

<add key="Telerik.Skin" value="Metro" />

Everything's good, but the embedded icon on my RadButton is not using the Metro icon. Here's the markup for the button:

<telerik:RadButton ID="rbCreateNew" runat="server"

Text="Create New">

<Icon PrimaryIconCssClass="rbAdd" />

</telerik:RadButton>

In the attached image, the "Create New" button is my button, and the "Add" button is from the RadButton embedded icons demo page.

I want my "Create New" button plus sign to look like the "Add" plus sign (black instead of green). I tried setting the Skin directly in the RadButton control attributes, but it didn't change anything. What am I missing here?

I am using 2013.3.1114.45.

How to block malicious files while uploading

Hi ,

I encountered a scenario i.e. where we have to stop uploading of .exe or .bat files when their extension is changed to acceptable extension (.txt,.html,.htm,.odt,.rtf,.doc,.docx). I have tried to find a solution by using .NET code where I have used header codes of different file extensions, but header codes for .html and .htm get changed and doesn't seem to have a fixed header code. I have used Mime/Extension type but it didn't work. Looking for a solution through Telerik Controls.

Thanks,
Chaitanya.

IE10 vs. Firefox

Hi!

while testing the RadDiagram I noticed that the text within the shapes is higher aligned when using the Internet Explorer 10. Firefox renders the text vertically centered. Does anybody know a CSS-Trick to "fix" the IE10-behaviour?

Best regards,
Hans
