In my project, I have INGRAGISTICS 11.1 version. I’m getting the issue in UltraCombo control. Unable to tab out from control.

When we try to find the cause, we observed that OnValidating is failing (always e.cancel = true is returning).

I have XML entity data binding, in my form.

Binding sample code:

this.cmbListC.DataBindings.Add("Value", xKey, "InnerXml");

this.cmbListC.DataBindings.Add("Text", xValue, "InnerXml");

Why always e.cancel is retuning true when data source is null.
