[Loyal User]

hello all, 
I have 2 textbox as shown in code below : 

<telerik:GridTemplateColumn UniqueName="guarantyAmount" HeaderText="<%$Resources:Strings,amount  %>">
                    <ItemTemplate>
                        <asp:Label Text='<%# Eval("WARRANTY_AMOUNT")%>' runat="server" id="warrantyAmountText">
                            </asp:Label>
                    </ItemTemplate>
                   <EditItemTemplate>

                       <telerik:RadNumericTextBox runat="server" id="warrantyAmount" ClientEvents-OnValueChanging="warrantyAmount_ValueChanging"></telerik:RadNumericTextBox>
                        </EditItemTemplate>
                   </telerik:GridTemplateColumn>

                  <%--<telerik:GridBoundColumn DataField="REAL_VALUE" HeaderText='<%$Resources:Strings,realValue %>' UniqueName="guarantyRealValue"/>--%>
              <telerik:GridTemplateColumn UniqueName="guarantyRealValue" HeaderText="<%$Resources:Strings,realValue  %>">
                    <ItemTemplate>
                        <asp:Label Text='<%# Eval("REAL_VALUE")%>' runat="server" id="realValueText">
                            </asp:Label>
                    </ItemTemplate>
                   <EditItemTemplate>

                       <telerik:RadNumericTextBox runat="server" id="realValue"></telerik:RadNumericTextBox>
                        </EditItemTemplate>
                   </telerik:GridTemplateColumn>

what i want is to create  " warrantyAmount_ValueChanging " js function that read input value from "warrantyAmount " textbox and put them in "realValue" ..

how can i achieve that ??

Hi Elsy,

Since the controls are rendered in the same NamingContainer you can try the following:

function warrantyAmount_ValueChanging(sender,args) {
          var value = args.get_newValue();
          var realValue = $find(sender.get_id().replace("warrantyAmount", "realValue"));
          realValue.set_value(value);
      }

The code logic above obtains a reference to the realValue RadNumericTextBox by modifying the last part of the warrantyAmount numeric in order to get the realValue id. Later using $find() we reference the client-object of the control and set it's value.
