Hi,
What is the best way to validate a raddropdownlist? I'v looked at the _Validating Event but this appears to only fire when you select another control.
When I try the selectedvlue_changed this appears to fire when the control is being databound etc.
Any help or pointers would be great.
Thanks

Thank you for writing.
By default, WinForms controls are validated on Leave and this behavior is normal.
You can put your validation logic at the SelectedIndexChanged event, for example:
radDropDownList1.DataSource = dataTabel1;//this will fire SelectedIndexChanged event with Selectedindex = 0radDropDownList1.SelectedIndexChanged+= radDropDownList1_SelectedIndexChanged;//subscribe for event after the databingingvoid radDropDownList1_SelectedIndexChanged(objectsender, Telerik.WinControls.UI.Data.PositionChangedEventArgs e){ validate...}I hope this helps. Don't hesitate to contact us if you have other questions.
