Hi, I have a RadButton that is supposed to open a radwindow when the "OnClientClicked" is fired.  However, the first time this gets fired, nothing happens.  The second time I click on the button...the radwindow opens up.  Am I missing some code?  I am basing this on your demo: http://demos.telerik.com/aspnet-ajax/button/examples/slideshow/defaultcs.aspx.

Here is the code that I have:

I can use a plain old button, and it fires off without a second click, but I would really like to use the radbutton since that will keep my styling the same.

Thanks!

Hi,

I'm displaying a Combobox with multiple item selection by means of a checkbox. Does not allow custom text. The problem is that the default text displays always the first item. Is there any way to display the default text as blank or a custom text (by not setting the 'Allow Custom Text' property to true?)

Thanks.

is it possible to combine combobox with paging
if yes, can you give some examples of how to do it.

thanks in advance

Hello,

I have a RadGrid with nested tables, for now called parent and child. It is a business rule that no parents can be childless, and that only the children can be removed. This results in a situation where the parent will have to be deleted when the last child is deleted.

At the moment, in the OnDeleted method, I am using to remove the parent item, after checking if the parent is now empty.

This results in a ArgumentOutOfRangeException at:

I assume because it's looking for a non-existent parent element when trying to create the now empty detailtable.

Can anyone help me resolve this situation. Basically I want the parent item removed when a child item is removed. I tried using the NeedDataSource event to check for empty parents and remove them directly on the database, but I'm not having much success with assigning already existing DataSources to the master and detail tables.

Thanks
