GridView的RowCommand事件不触发

问题描述：

我有一个GridView看起来是这样的：

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>

下面是 RowCommand ：

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

单击该按钮在不触发的 RowCommand 事件都没有。然而， RowCommand 火灾时，我点击GridView的寻呼机页索引。

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.

答

您必须的不可以绑定在Page_Load中回传网格，只有当一些改变，导致电网重新加载数据（FE排序，寻呼），并且仅在适当的事件处理程序。

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：是否禁用ViewState的地方

Another possible reason: Have you disabled ViewState somewhere?
