[Solved] Related Combobox?

[Patrick Wilson]

Wanting to implement a simple related combobox inside the insert/edit mode of a radgrid. I would like for the user to select a value from the first field (a combobox) which will populate the next field which is a textbox.

Hello Patrick,

You can try out the following code to access the textbox in the edit row on changing the selection in a RadComboBox in the same edit row:
aspx:

<telerik:GridTemplateColumn DataField="FirstName" UniqueName="TemplateColumn" >
     <ItemTemplate>
      ....
     </ItemTemplate>
     <EditItemTemplate>
         <telerik:RadComboBox ID="RadComboBox1" AutoPostBack="true" DataSourceID="SqlDataSource1" DataTextField="FirstName" runat="server" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">      </telerik:RadComboBox>
     </EditItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridBoundColumn DataField="FirstName" HeaderText="BoundColumn" UniqueName="BoundColumnUniqueName">
</telerik:GridBoundColumn>

c#:

protected void RadComboBox1_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
    {
        RadComboBox combo = (RadComboBox)o;
        GridEditableItem editItem = (GridEditableItem)combo.NamingContainer;
        TextBox txtbx = (TextBox)editItem["BoundColumnUniqueName"].Controls[0];
        txtbx.Text = combo.SelectedItem.Text;

    }

Thanks
Princy.
