里面的UpdatePanel内的GridView通过LinkBut​​ton的触发完全回发 [英] Full postback triggered by LinkButton inside GridView inside UpdatePanel

问题描述

我有一个GridView一个UpdatePanel的内部。在模板字段是一个按​​钮，我使用的标志项目。在功能上，这工作正常，但按钮始终触发一整页回传，而不是局部回传。我如何获得按钮，触发部分回发？

解决方案

您需要在每一个注册的LinkBut​​ton作为AsyncPostBackTrigger。每排在你的GridView绑定后，你需要搜索的LinkBut​​ton，并通过code寄存器，如下所示：

 保护无效OrderGrid_RowDataBound（对象发件人，GridViewRowEventArgs E）
{
   LinkBut​​ton的磅= e.Row.FindControl（MarkAsCompleteButton）作为LinkBut​​ton的;
   ScriptManager.GetCurrent（本）.RegisterAsyncPostBackControl（磅）;
}
 

的ClientIDMode =自动识别为LinkBut​​ton的（见下面的评论）

I have a GridView inside of a UpdatePanel. In a template field is a button I use for marking items. Functionally, this works fine, but the button always triggers a full page postback instead of a partial postback. How do I get the button to trigger a partial postback?

<asp:ScriptManager ID="ContentScriptManager" runat="server" />
<asp:UpdatePanel ID="ContentUpdatePanel" runat="server" ChildrenAsTriggers="true">
    <ContentTemplate>
        <asp:GridView ID="OrderGrid" runat="server" AllowPaging="false" AllowSorting="false"
            AutoGenerateColumns="false">
            <Columns>
                <asp:TemplateField HeaderText="">
                    <ItemTemplate>
                        <asp:LinkButton ID="MarkAsCompleteButton" runat="server" Text="MarkAsComplete"
                            CommandName="MarkAsComplete" CommandArgument='<%# Eval("Id") %>' />
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:BoundField DataField="Name" HeaderText="Name" />
                <asp:BoundField DataField="LoadDate" HeaderText="Load Date" />
                <asp:BoundField DataField="EmployeeCutOffDate" HeaderText="Cut Off Date" />
                <asp:BoundField DataField="IsComplete" HeaderText="Is Completed" />
            </Columns>
        </asp:GridView>
    </ContentTemplate>
</asp:UpdatePanel>

解决方案

You need to register each and every LinkButton as an AsyncPostBackTrigger. After each row is bound in your GridView, you'll need to search for the LinkButton and register it through code as follows:

protected void OrderGrid_RowDataBound(object sender, GridViewRowEventArgs e)  
{  
   LinkButton lb = e.Row.FindControl("MarkAsCompleteButton") as LinkButton;  
   ScriptManager.GetCurrent(this).RegisterAsyncPostBackControl(lb);  
}  

ClientIDMode="AutoID" for the LinkButton (see comment below)
