GridView RowCommand 事件未触发 [英] GridView RowCommand event not firing

问题描述

我有一个看起来像这样的 GridView:

I have a GridView that looks something like this:

<asp:GridView 
    ID="GridView1"
    AllowPaging="true"
    OnRowCommand="RowCommand"
    OnPageIndexChanging="gridView_PageIndexChanging"
    Runat="server">
    <Columns>
        ...
        <asp:TemplateField>
            <ItemTemplate>
                <asp:Button ID="Button1" ButtonType="Button" CommandName="ItemExport" CommandArgument='<%# Eval("EXPORT") %>'
                    Text="Export" runat="server" />
            </ItemTemplate>
        </asp:TemplateField>
        ...
    </Columns>
 </asp:GridView>

这是RowCommand:

protected void RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "ItemExport")
    {
        // etc.
    }
}

单击按钮根本不会触发 RowCommand 事件.但是，当我单击 GridView 的寻呼机中的页面索引时，会触发 RowCommand.

Clicking the button is not firing the RowCommand event at all. However, RowCommand fires when I click a page index in the GridView's pager.

推荐答案

您必须不在 Page_Load 中的回发时绑定您的网格，只有当某些更改导致网格重新加载数据时(fe Sorting,分页)并且仅在适当的事件处理程序中.

You must not bind your grid on postbacks in Page_Load, only when something changed that causes the Grid to reload data(f.e. Sorting,Paging) and only in the appropriate event-handlers.

另一个可能的原因:您是否在某处禁用了 ViewState?

Another possible reason: Have you disabled ViewState somewhere?
