Cell update

[lm]

I am pretty new to telerik I am playing around with this for last 2 days. I need your help.  I have a grid with Templatecolumns which have text boxes as their edititem there are about 12 such columns. When I edit one cell of a row the cells on its left  need to be updated. 

I used changeevent of the textbox to capture the item. Not sure if that is the right approach.I 
I coudl get the rowindex of the cell being edited, how do I fidn the column being edited. 

TIA

Hi Levanya,

I would like to ask you to elaborate more on your scenario. Do you want to change the values client-side or server-side. If you want to change the value client-side you can directly obtain a reference to the other text box by modifying the id of the sender and using $find. For example if you have two columns defined like this:

<telerik:GridTemplateColumn DataField="A" UniqueName="column1">
                        <ItemTemplate>
                            <%# Eval("A") %>
                        </ItemTemplate>
                        <EditItemTemplate>
                            <telerik:RadTextBox runat="server" Text='<%# Bind("A") %>' ID="TextBox1EditItemTemplate"></telerik:RadTextBox>
                        </EditItemTemplate>
                    </telerik:GridTemplateColumn>
                    <telerik:GridTemplateColumn  DataField="B" UniqueName="column2">
                        <ItemTemplate>
                            <%# Eval("B") %>
                        </ItemTemplate>
                        <EditItemTemplate>
                            <telerik:RadTextBox runat="server" ClientEvents-OnValueChanged="ValueChanged"
                                Text='<%# Bind("B") %>' ID="TextBox2EditItemTemplate"></telerik:RadTextBox>
                        </EditItemTemplate>
                    </telerik:GridTemplateColumn>

In the ValueChanged event handler you can change the text in the other column like demonstrated below:

function ValueChanged(sender, args) {
           $find('<%=RadGrid1.ClientID%>').get_masterTableView().get_dataItems();
           var textBoxInColumn2 = $find(sender.get_id().replace("TextBox2EditItemTemplate", "TextBox1EditItemTemplate"));
           textBoxInColumn2.set_value(args.get_newValue());
       }

In attachments you can find the sample website in which this approach is implemented.
