推荐答案

这似乎是 PostBack 向我发出问题。



只有在未回复页面时才必须绑定网格。

因此，您需要在 Page_Load 事件中使用以下内容。

This seems to be a PostBack issue to me.

You must bind the Grid only when Page is not posting back.
So, you need to something like below in Page_Load Event.

private void Page_Load()
{
    if (!IsPostBack)
    {
        BindYourGrid();
    }
}

参考 - Page.IsPostBack Property [ ^ ]
