RADGRID inside a RADCOMBOBOX

[Omarr]

Hi, I have a RADGRID as a template item inside a RADCOMBOBOX. It is loaded on demand. Now whenever I try to type anything on the text section of RADCOMBOBOX, it throws an error:
"Script control <grid_name> is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors(). Parameter name: scriptControl."

Hello Omarr,

The combobox should not be in Load on demand mode. EnableLoadOnDemand should be set to False.
That is because you have only one item in the combobox.

You can see a working example here: Load on demand grid in combobox

I got most of the part working...but need to know how will it work if I enter a text in the combo box? I got it working if I enter the string in the combobox text field, but I have to PRESS ENTER key inorder to get the refreshed grid. What should I do to trigger the search on every key I press (like a simple combobox works when its Filter property is set to "Contains").

Hi Omarr,

You can subscribe to the OnClientKeyPressing event and use the sender.get_text() to get the currently typed text. Here you can make an ajax request to the server and filter your grid.

I attached the same code as what  onClientDropDownOpening function has; but got a javascript null object error. Can you be more specific and write a sample code for me?
Thanks
