                       开发者_运维问答     </td>
                        </tr>
                    </table>
                </div>
            </asp:Panel>
        </ContentTemplate>
    </asp:UpdatePanel>

My .cs:

protected void txt_evaluateWeights_TextChanged(object sender, EventArgs e)
    {

        calc();
        int index = ((System.Web.UI.WebControls.GridViewRow)(((RadTextBox)sender).Parent.NamingContainer)).DataItemIndex;

        ((RadTextBox)gv_Evaluation.Rows[index + 1].Cells[3].FindControl("txt_evaluateWeights")).Focus();


    }

Well you need to use an id selector, i.e. prefix with #:

$(...).scollTo($('#<%= txt_evaluateWeights.ClientID %>'));
