Hi,

 I am trying to use RadComboBox with check box items - using this MultiselectionComboBox http://www.telerik.com/forums/multi-select-combobox-column-b1333dcb19e7#A84Ijx2y90Cke9PV3xKCOA

Then I added a button to this view and after checking some check boxes I click on this button - nothing happens and I need to click on it second time in order to trigger the desired action.

Looks like one click is "wasted" on closing the combobox. Is there any way to prevent this so that after checking any check box in combobox clicking on the button will actually trigger button click event?

Thanks

Victor

Hi Victor,

The observed behavior is not related with RadComboBox, but it is one caused by the Framework itself - if you replace RadComboBox with the native WPF ComboBox the exact same behavior will be observed. However, still we were able to find an approach that could help you achieve the desired - please, check the following link:
http://stackoverflow.com/questions/9710013/how-to-get-a-combobox-to-appropriately-set-focus-directly-after-the-popup-closes

Basically, it demonstrates how to move the focus to the Button when the Popup gets clicked. We have also modified the sample you sent us with it and it seems it works as expected - attached you could find the modified project.

We hope this will help you.

Thank you.

I thought so but wanted to see if you have any good solution. And it works.

Actually, I had this before asking you:

         private void RadComboBox_OnDropDownClosed(object sender, EventArgs e)

        {
            if (BtnClickMe.IsMouseOver)
            {
                Button_Click(sender, null);
            }
        }

and it works too.

Thanks again.

Victor
