Required Validation for DropDown List

[livezone]

Hi
I have created a Drop Down list with a validation required. I added a field dynamically at the start which will be the initial value

Dim dtrDepartment As SqlDataReader
dtrDepartment = cmdDepartment.ExecuteReader()
dropDepartment.DataSource = dtrDepartment
dropDepartment.DataValueField = "Department_ID"
dropDepartment.DataTextField = "Department_Text"
dropDepartment.DataBind()
dtrDepartment.Close()
rfdvDepartment.InitialValue = lblDepartment.Text
dropDepartment.Items.Insert(0, New ListItem(lblDepartment.Text, -1))


Validation is like that

<asp:RequiredFieldValidator ID=&quot;rfdvDeparmtnet&quot; Runat=&quot;server&quot; ErrorMessage=&quot;Select your Store/Department&quot; ControlToValidate=&quot;DropDepartment&quot; Display=&quot;Dynamic&quot;></asp:RequiredFieldValidator>

As it shows the inital value as &quot;Select Department&quot; but it did not give me an error message if someone did not select anyother value than &quot;Select Department&quot;

Please guide
Thanks

Ignore it.

I have found the solution

rfdvDepartment.InitialValue = -1

will work

Thanks
