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.

Hi Najid,
The experienced behavior is the default one, when load on demand is used. Please refer to the following help article discussing this matter.
When using load on demand, the items of the RadCombobox are not presented on the server-side and you could access only the Text and SelectedValue of the control.
All the best,
