Index Change event for Combobox of gridtemplateColumn in Telerik

[Ankur]

I can write a code. In this I can take a Template Column & in this I build a RadCombobox. When it's Index changed I want to affect the below text box. Link the selected value of the Combo box is set as Text on Below TextBox. Combo Box & Text Box are different Controls of Different Template Column.

I can Write Control of Combo box like this :

<telerik:RadComboBox ID="cmbGID" runat="server" DataSourceID="SqlDataSource8" DataTextField="Name"
                        DataValueField="ID" AutoPostBack="True" OnSelectedIndexChanged="cmbGID_SelectedIndexChanged">

But I don't know the parameters of this event like this :

protected void cmbGID_SelectedIndexChanged()
{
       //code...
}

Any one plz tell me that parameters & tell me is that possible to set txtValue.Text = cmbGID.SelectedValue.ToString()...???
& also I can fire a query using cmbGID.SelectedValue & set the other combobox's(this is also a control of template column) datasource...

Note: This all controls of Template Column are InsertItem Template...
