如何显示和隐藏内部GridView列

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        // 获取当前行的数据
        DataRowView rowView = (DataRowView)e.Row.DataItem;
        
        // 根据条件判断是否显示或隐藏列
        if (rowView["ColumnName"].ToString() == "Hide")
        {
            // 隐藏列
            e.Row.Cells[columnIndex].Visible = false;
        }
        else
        {
            // 显示列
            e.Row.Cells[columnIndex].Visible = true;
        }
    }
}
