I'm using Version 2008.1.415.20 of RadComboBox.  After a postback when using the LoadOnDemand=true to fetch the items, the Items collection is null.  

The SelectedValue field seems to be populating with the text value in the combo box.  Unfortunately, I need the value of what the DataValue field was, and not the DataTextField. 

Any help here would be appreciated.  Thanks.

Hi Rob,

The Items collection is not persisited on the server by design if the items are laoded on demand. However SelectedValue and Text property should returns correct values. I suggest you try our latest official release 2008.1.619. You can download it from your account.

Also,please see our online example. It works as expected at our side.

If this does not help you,please open a support ticket and send us sample running project to test it locally.

It is difficult to tell if its working as expected.  In the example you posted, you set datavalue and datatext to the same value, so on the post back its impossible to tell if there is a problem:

                    RadComboBox1.Items.Add(new RadComboBoxItem(data.Rows[i]["CompanyName"].ToString(), data.Rows[i]["CompanyName"].ToString() )); 

Here is what I want,

                    RadComboBox1.Items.Add(new RadComboBoxItem(data.Rows[i]["CompanyName"].ToString(), data.Rows[i]["CompanyID"].ToString() )); 

When I do this in my code, I expect to see CompanyID as the value, instead I see CompanyName.
