SelectedValue Not Working?

[Bryan Kowalchuk]

I have tried everthing to get the SelectedValue of a radCombo to work, but it always seems to have a value of "1".
I have a simple scenario, a radcombo in ASP.FormView in edit mode.

The combo definition looks like:

<telerik:RadComboBox ID="EmployeePotentialCombo" runat="server" DataSourceID="EmployeePotentialList"
    DataValueField="eptID" Text="Employee Potential:" DataTextField="eptDesc" Width="350px"
    EmptyMessage="Select Employee Potential" Label="Potential:">
</telerik:RadComboBox>

The list populates correctly.

First I tried to set the value this way:

<telerik:RadComboBox ID="EmployeePotentialCombo" runat="server" DataSourceID="EmployeePotentialList"
    DataValueField="eptID" Text="Employee Potential:" DataTextField="eptDesc" Width="350px"
    EmptyMessage="Select Employee Potential" Label="Potential:" SelectedValue='<%# Bind("eptID") %>'>
</telerik:RadComboBox>

With no results. Next attempt was with code-behind:

protected void FormView1_DataBound(object sender, EventArgs e)
{
    DataRowView drv = (DataRowView)FormView1.DataItem;
    RadComboBox combo = (RadComboBox)FormView1.FindControl("EmployeePotentialCombo");
    combo.SelectedValue = drv["eptID"].ToString();
   // combo.SelectedValue = "3";
}

Setting the value from the DataRowView (null) or forcing a value to "3" had no effect, SelectedItemValue was always "1"

Any ideas?

Update: The first scenario worked OK except for nul values from the database. Is there a way to show the empty message for nulls?

Hi Bryan Kowalchuk,

The empty message shows only if the RadComboBox is not read-only (AllowCustomText=True). Then you can force the empty message to apply if you clear the selection in the RCB by calling ClearSelection() or the control has no Items.

I hope this helps.

Best wishes,
