Hello.
I build a Combo from a table
DataTable dt = lb.clsDB_user_store_gen.get_dt_for_all_user_store();
cboReporter.DataSource = dt;
cboReporter.ValueMember = "uid";
cboReporter.DisplayMember = "displayName";
I put the form in ADD MODE, and wand to say in the first record "Select a Reporter"
It works the first time. When I update the record and clear the form, I call the code below. this then add the text again. (sorry wanted to add small video, but mp4 not supported)
// cboReporter
cboReporter.SelectedText = "";
cboReporter.SelectedText = "Select a Reporter";
// cboAssignee
cboAssignee.SelectedText = "";
cboAssignee.SelectedText = "Select a Assignee";

According to the provided code snippet, it is not clear what are the exact records available in RadDropDownList. However, if you have the first record that holds the text "Select a Reporter", instead of setting the SelectedText property, simply set the SelectedIndex to 0 and thus the first item's text will be displayed. Alternatively, if you don't have a specific record that holds "Select a Reporter", it is suitable to use the embedded label functionality:

In case you are still experiencing any further difficulties, it would be greatly appreciated if you can provide a complete code snippet that replicates the undesired behavior if we copy/paste the code in a brand new project. Thus, we would be able to provide further assistance. Thank you in advance.
I hope this information helps. If you need any further assistance please don't hesitate to contact me.
