ASP.NET 2.0 - DataGrid与tbody / thead [英] ASP.NET 2.0 - DataGrid with tbody / thead

问题描述

解决方案

当我喜欢这个文件的时候，有没有办法让DataGrid控件渲染tbody和HTML元素？通过user186197回答，该博客使用反射，在非完全受信任的主机环境中可能会出现问题。这是我们使用的，没有黑客：

  public class THeadDataGrid：System.Web.UI.WebControls.DataGrid 
 { 
 protected override void OnPreRender（EventArgs e）
 {
 this.UseAccessibleHeader = true; //确保我们呈现TH，而不是TD 
 
 Table table = Controls [0] as Table; 
 
 if（table！= null&& table.Rows.Count> 0）
 {
 table.Rows [0] .TableSection = TableRowSection.TableHeader; 
 table.Rows [table.Rows.Count  -  1] .TableSection = TableRowSection.TableFooter; 
} 
 
 base.OnPreRender（e）; 
} 
} 
  

Is there a way to get the DataGrid control to render the tbody and thead HTML elements?

解决方案

While I like the answer by "user186197", that blog post uses reflection, things might go wrong in non-full-trusted hosting environments. Here's what we use, no hacks:

public class THeadDataGrid : System.Web.UI.WebControls.DataGrid
{
    protected override void OnPreRender(EventArgs e)
    {
        this.UseAccessibleHeader = true; //to make sure we render TH, not TD

        Table table = Controls[0] as Table;

        if (table != null && table.Rows.Count > 0)
        {
            table.Rows[0].TableSection = TableRowSection.TableHeader;
            table.Rows[table.Rows.Count - 1].TableSection = TableRowSection.TableFooter;
        }

        base.OnPreRender(e);
    }
}
