OnItemRequested event is not working

[prayag ganoje]

Hello,

I am using RadTabStrip. Inside this multiple tab strip there are usercontrols loaded. In one of the user control I have a RadComboBox with OnItemRequested even. I want to load this combobox with the selected values using OnItemRequested event.

But the OnItemRequested  event handeler is not envoked when i try to enter some text in the RadComboBox.

Can you please guide me ? what could be the possible way to make to enable to call this event handler ?

Note: I used EnableAutomaticLoadOnDemand="true" and also put the all controls in UpdatePanel.

Thanks,
Prayag

Hi Prayag,

You should set EnableLoadOnDemand property to true (not EnableAutomaticLoadOnDemand) in order to fire ItemsRequested event as explained here.

Hey, 

Does this/should this work for a ComboBox with the option 'EnableCheckAllItemsCheckBox' set to 'true'? I have over 1000 items in a RadComboBox and it has not been working. It has been giving me the following error on Internet Explorer: 

"A script on this page is causing your web browser to run slowly. If it continues to run, your computer might become unresponsive."

Please let me know as soon as possible,
Thank You,
Asma

This has been added  to the RadComboBox properties:
OnClientDropDownClosed="SR"

& the javascript for sr is:
        function SR(s, a) {
            if (s.get_text().length < 1) {
                a.set_cancel(true);
                s.hideDropDown();
            }
        } 


But this did not help... I am still experiencing the issue
Please help as soon as possible, your assistance is greatly appreciated!

Hello,

Using the load on demand mechanism along with the CheckBoxes feature, is not a supported scenario. You could find more info on this matter at the following link : RadComboBox / CheckBox support.
