Working with Combobox Column in grid

[Rahul]

Hi,
I am new to telerik controls. I am working on below scenario 
I have  one Rad Grid which will have 3 columns out of which one is dropdown column. I am able to populate the combo box on page load but I want that Values in other two columns should get populated based on what value is selected in combo box column.

Please let me know how to do this.

Hi rahul,

Im not clear about your requirement, i guess you want to access a dropdownlist in GridTemplateColumn and fill the other columns based on its value. Here is a sample code snippet please have a look into this, if it doesn't help, provide your code if any and elaborate on your requirement.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server">
    <MasterTableView DataKeyNames="OrderID">
        <Columns>
            <telerik:GridTemplateColumn>
                <ItemTemplate>
                    <asp:DropDownList DataSourceID="SqlDataSource1" AutoPostBack="true" DataTextField="ShipCountry"
                        DataValueField="ShipCountry" ID="DropDownList1" runat="server" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
                    </asp:DropDownList>
                </ItemTemplate>
            </telerik:GridTemplateColumn>
            <telerik:GridTemplateColumn>
                <ItemTemplate>
                    <asp:Label ID="Label1" runat="server" Text=""></asp:Label>
                </ItemTemplate>
            </telerik:GridTemplateColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

C#:

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
  DropDownList drop=(DropDownList)sender;
  GridDataItem item = (GridDataItem)drop.NamingContainer;
  string value = drop.SelectedValue;
  Label lbl = (Label)item.FindControl("Label1");
  lbl.Text = "Your Text";
}

Thanks,
