I have a drop down that holds around 6000 items.
If EnableAutomaticLoadOnDemand is set to "True" OnSelectedIndexChanged for RadComboBox1.SelectedItem is NULL.
This is not the case if EnableAutomaticLoadOnDemand is set to "False"
Because I have so many items in my dropdown I have EnableAutomaticLoadOnDemand set to "True". Is this expected behavior? and if so how can I workaround this?
Thanks
Here are the properties I have set on the Combo-box.
