[Solved] OnClientSelectedIndexChanged doesn't fire when selection cleared

[Mark]

I am successfully subscribing to OnClientSelectedIndexChanged when the user selects an item, but this does not fire when a user clears the selection.

Is there any way to pick up this event?

Hello Mark,

You can subscribe to the OnClientKeyPressing event. It fires everytime when a key of the keyboard is pressed and the input of RadComboBox is focused.

Hello emidio rana,

Since you are Data Binding the ComboBox you could use the DataTextField and DataKeyField properties to map the Text and Value properties of Items to columns of the underlying data rows (more info here).

Here and here you could find two examples of a ComboBox with CheckBoxes. Are the useful to you?
