RadCombobox KeyBoard

Hi everyone, I'm curently writing a 100% keyboard application (of course you can use the mouse too but it's faster when you use the keyoard only) . My prolem is when I have more than 1 result to a query I need too show the result and let the user choice which one he want to use... But I use the SelectedItemChange Event to set something else. So when the user use the keyDown to move in the combobox that call the SelectedItemChange Event but I don't want this. With the VS Combobox I setted a boolean to true when the user pressed the keydown , but in the RadCombobox the keydown event comes before the SelectedItemChange Event so my way is impossible. If you can just show me an other way I would be happy.

Thanks and sorry for all english mistakes

Hello Alexandre,

As far as I understand your scenario, you are actually using the SelectedIndexChanged event for a specific purpose and you would not like to execute the code in the event handler when the user changes the items using the Up/Down keys.

Indeed, unlike the standard MS combobox, the RadComboBox fires the SelectedIndexChanged before the KeyDown event. So, in your case, as a workaround I would suggest using the RadTextBoxItem.PreviewKeyDown event instead of setting the boolean flag. This event can be accessed as shown below:

this.radComboBox1.ComboBoxElement.TextBoxElement.TextBoxItem.PreviewKeyDown += new PreviewKeyDownEventHandler(TextBoxItem_PreviewKeyDown);

I hope this helps. If you have any additional questions, please don't hesitate to write us again.
