I have a grid with a textbox and a ClientSelectColumn. I would like to copy the value from one column into the textbox in an itemTemplate column when the selectcolum checkbox is checked. I would like to do this client-side as posting back and using server-side code can take as much as 2 seconds - unacceptable for high-volume data entry.

I would also like to do this for all columns when the checkbox in the header is checked.

TotalAmt would be copied into AmtApproved. I also need to be able to deselect and have the value clear if it exists in the textbox.

Thank you in advance for your help!

 <telerik:GridBoundColumn DataField="TotalAmt" DataType="System.Decimal" FilterControlAltText="Filter TotalAmt column" HeaderText="TotalAmt" SortExpression="Total Due" UniqueName="TotalAmt" DataFormatString="{0:F}" HeaderStyle-HorizontalAlign="Right" ItemStyle-HorizontalAlign="Right" ItemStyle-Width="75px" HeaderStyle-Width="75px">
                                </telerik:GridBoundColumn>
<telerik:GridTemplateColumn HeaderText="Amount Approved" UniqueName="AmtApproved" HeaderStyle-Width="55px" ItemStyle-Width="55px" HeaderStyle-HorizontalAlign="Right" ItemStyle-HorizontalAlign="Right">
                                    <ItemTemplate>
                                        <asp:TextBox ID="AmountApproved" runat="server" Width="55px" OnTextChanged="AmountApproved_TextChanged" AutoPostBack="true" CssClass="numericAlign"></asp:TextBox>
                                    </ItemTemplate>
                                </telerik:GridTemplateColumn>
                                <telerik:GridClientSelectColumn HeaderText="Pay in Full" UniqueName="ClientSelectColumn">
                                </telerik:GridClientSelectColumn>

Hi Thomas,

I've created a sample RadGrid web site to demonstrate how you can achieve the requested functionality. Please run the attached application and let me know if it works for you.
