您应该使用javascript在客户端执行此操作。



因此您可以处理GridView的RowDataBound事件将其添加到Delete-Button的OnClientClick：

You should do that on clientside with javascript.

Therefore you can handle GridView's RowDataBound event to add this to the Delete-Button's OnClientClick:

protected void gvShowQuestionnaires_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        // reference the Delete LinkButton
        LinkButton db = (LinkButton)e.Row.Cells[3].Controls[0];

        db.OnClientClick = "return confirm('Are you certain you want to delete this questionnaire?');";
    }
}
