使用ajax控件检查是否为空 [英] Use ajax control for check empty

问题描述

我可以使用Ajax控件来验证模板"字段中的空文本框吗.

Could I use the Ajax Control,for validating the empty textBox which is in Template field.

<asp:TemplateField HeaderText="KRA Weightage" AccessibleHeaderText="txtKRAWtg" >
                           <ItemTemplate>
                               <asp:Label ID="Label1" runat="server" Text='<%# Bind("KRAWeightage") %>'></asp:Label>
                               <asp:TextBox ID="txtKRAWtg" runat="server" Height="20px" Width="43px" ValidationGroup="KRAWeightage"></asp:TextBox>
                               <asp:RequiredFieldValidator ID="rfdKRAWtg" runat="server"

                                   ErrorMessage="KRA can't empty" ControlToValidate="txtKRAWtg" ValidationGroup="KRAWeightage"></asp:RequiredFieldValidator>
                           </ItemTemplate>

通过Require Field Validator，我想使用ajax控件向用户显示警报消息.

With the Require Field Validator,I would like to use ajax control to show alert message to user.
