Hi,

Try the following code to achieve your scenario.
C#:

protected void RadGrid1_UpdateCommand(object sender, GridCommandEventArgs e)
   {
       GridEditableItem item = (GridEditableItem)e.Item;
       RadComboBox combo = (RadComboBox)item.FindControl("RadComboBox1");
       string value = combo.SelectedValue.ToString();
   }

Thanks,

Thanks for ur reply..

same code i have tried already but it's not working ,selected value is returning null..
i guess some other problem is there in my code..
plz check the below code

  <telerik:GridTemplateColumn HeaderText="ProposalType"
                                            SortExpression="ProposalType">
                                            <ItemTemplate>
                                                <%# DataBinder.Eval(Container.DataItem, "ProposalCodeId")%>
                                            </ItemTemplate>
                                            <EditItemTemplate>
                                                <telerik:RadComboBox ID="ProposalType" runat="server"
                                                    DataSourceID="PropDataSource" DataTextField="ProposalCode"
                                                    DataValueField="InternalID" EnableLoadOnDemand="True"
                                                    Text='<%# Bind("ProposalCodeId")%>' Width="60px">
                                                </telerik:RadComboBox>
                                            </EditItemTemplate>
                                        </telerik:GridTemplateColumn>


  <asp:SqlDataSource ID="PropDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:Payment %>"
        SelectCommand="Select InternalID,ProposalCode,ProposalName from tbl_PymtProposalType"></asp:SqlDataSource>

if you could give me any example using combobox in grid would be better to understing..

Hi,

Here is the full code that I tried which worked as expected.
aspx:

<telerik:RadGrid ID="RadGrid1" AutoGenerateEditColumn="true" runat="server" DataSourceID="SqlDataSource2" AutoGenerateColumns="false" OnUpdateCommand="RadGrid1_UpdateCommand">
  <MasterTableView>
    <Columns>
     <telerik:GridTemplateColumn DataField="ShippedDate">
        <EditItemTemplate>
          <telerik:RadComboBox ID="ProposalType" runat="server" DataSourceID="SqlDataSource1" DataTextField="EmployeeID" DataValueField="LastName" Text='<%# Bind("OrderID")%>' Width="60px"></telerik:RadComboBox>
        </EditItemTemplate>
     </telerik:GridTemplateColumn>
   </Columns>
 </MasterTableView>
</telerik:RadGrid>
    <asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
        SelectCommand="select  top 20 * from [Orders]"></asp:SqlDataSource>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
        SelectCommand="select  EmployeeID,LastName from [Employees]"></asp:SqlDataSource>

C#:

protected void RadGrid1_UpdateCommand(object sender, GridCommandEventArgs e)
   {
       GridEditableItem item = (GridEditableItem)e.Item;
       RadComboBox combo = (RadComboBox)item.FindControl("ProposalType");
       string value = combo.SelectedValue.ToString();
   }
