如何在网格视图中的控件中使用更新面板. [英] How to use Update Panel for the control in the gridview.

问题描述

大家好，

我的更新面板有问题，请帮助我解决此问题，
问题是，我有一个gridview，其中一个文本框控件的autopostback设置为true，而更新面板则设置为整个页面.当我单击外部的提交按钮时，gridview页面没有刷新，这意味着更新面板正在工作.并且当gridview激发页面中的文本框控件正在刷新时，它不应该刷新(更新面板在这里不起作用)..帮助我如何解决此问题..

我的代码就是这样..

<asp:UpdatePanel ID="UpdatePanel2" runat="server">
    <ContentTemplate>
        asp:GridView ID="gVAppraisal" runat="server" AutoGenerateColumns="False"
        <columns>
<asp:TemplateField HeaderText="Manager" ItemStyle-Width="80px" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:TextBox ID="txtWT" runat="server" Width="30px" AutoPostBack="true"                                                           OnTextChanged="txtWT_TextChanged"></asp:TextBox>%                                            <asp:RequiredFieldValidator ID="RFTH" runat="server" ControlToValidate="txtWT" ValidationGroup="save" Display="Dynamic" ForeColor="Red" ErrorMessage="Please Enter the missed percentages, check at the red colored star symbol">*</asp:RequiredFieldValidator>                                           </ItemTemplate>
</asp:TemplateField>
</columns>
        </asp:GridView>
        <asp:Button ID="btnSave" runat="server" CssClass="button" OnClick="btnSave_Click"

            Text="Save" ValidationGroup="save" ToolTip="Save" />
    </ContentTemplate>
        <Triggers>

<asp:AsyncPostBackTrigger ControlID="btnSave" EventName="Click" />

            </Triggers>
</asp:UpdatePanel>

尝试以下代码.将您的文本框保留在更新面板中

try the following code. keep your textbox in update panel

<asp:TemplateField>
        <ItemTemplate>
            <asp:UpdatePanel runat="server">
                 <ContentTemplate>
                    <asp:TextBox ID="txtTestGrid" runat="server" AutoPostBack="True"

                                   ontextchanged="txtTestGrid_TextChanged"></asp:TextBox>
                  </ContentTemplate>
            </asp:UpdatePanel>
        </ItemTemplate>
</asp:TemplateField
