c# - 使用 rowdatabound 计算列数

Question

我需要在事件 rowdatabound 中找到 gridview 中的总列数。有什么办法吗？下面是我的一些代码:

   protected void gvEmployee_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            LinkButton lnkView = new LinkButton();
            lnkView.ID = "lnkView";
            lnkView.Text = "View";
            lnkView.Click += ViewDetails; 
            e.Row.Cells[3].Controls.Add(lnkView);
        }

Answer 1

您可以将 sender 转换到 GridView 并获取计数。

protected void gvEmployee_RowDataBound(object sender, GridViewRowEventArgs e)
{      
    if(!(sender is GridView))
        return;

    GridView gridView = (GridView) sender;
    var colCount = gridView.Columns.Count;

   //Your code
}
