[Solved] Related Combo Boxes as Edit Item Template in a Grid

[Suresh Mishra]

Hi,

I have a combobox in the edititemtemplate of two of my grid cloumns.  How can I relate the two, so that the second combo box gets refreshed everytime the value of the first combo box is changed?  Please note that both there columns are defined as edititems.  The edit mode for the MasterTableView is "inplace."

Your early reply will be greatly appreciated.

Thanks.

Suresh

Hello Suresh,

You can try out the following code to populate a combobox based on the selection in another combobox in the grid:
aspx:

<telerik:GridTemplateColumn UniqueName="ContactTitle" HeaderText="ContactTitle">
     <EditItemTemplate>
         <telerik:RadComboBox ID="RadComboBox1" AutoPostBack="true" runat="server" SelectedValue='<%# Bind("ContactTitle") %>' DataSourceID="SqlDataSource1" DataTextField="ContactTitle"  OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">
         </telerik:RadComboBox>
     </EditItemTemplate>
</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn UniqueName="TemplateColumn">
     <EditItemTemplate>
         <telerik:RadComboBox ID="RadComboBox2"  runat="server">
         </telerik:RadComboBox>
     </EditItemTemplate>
</telerik:GridTemplateColumn>

c#:

 protected void RadComboBox1_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
    {
        RadComboBox rdcbx = (RadComboBox)o;
        GridEditableItem editedItem = rdcbx.NamingContainer as GridEditableItem;
        RadComboBox ddList = editedItem.FindControl("RadComboBox2") as RadComboBox;
        // change the data source for ddList here
         .....
    }

Thanks
