关于含TemplateColumn列的DATAGRID转EXCEL的问题请教

查了很多资料，感觉应该能解决的，但是一天时间过去了，还是无可奈何，请教了，如果没有解决方法，只好换方案了。
测试代码如下：
<%@ Page language="C#" %>
<%@ Import Namespace="System.Data" %><html>
<script runat="server">DataTable Store = new DataTable();
DataView StoreView;  void Page_Load(Object sender, EventArgs e) 
{
         if(Session["StoreData"] == null)
         {
            DataRow dr;
 
            Store = new DataTable();                  Store.Columns.Add(new DataColumn("Item", typeof(String)));
            Session["StoreData"] = Store;
            
            // Create sample data.
            for (int i = 1; i <= 4; i++) 
            {
               dr = Store.NewRow();
       dr[0] = "0.0%";
               Store.Rows.Add(dr);
            }                }
         else
            Store = (DataTable)Session["StoreData"];         StoreView = new DataView(Store);
         StoreView.Sort="Item";         if(!IsPostBack)                    
            BindGrid();
                 
      }void BindGrid() 
      {
         MyDataGrid.DataSource = StoreView;
         MyDataGrid.DataBind();
      }private void Button1_Click(object sender, System.EventArgs e)
{
//export to excel Response.Clear();
Response.Charset = ""; 
Response.Buffer= true;
Response.AddHeader("Content-Disposition", "attachment; filename=myXls.xls");
Response.ContentType = "application/vnd.ms-excel"; 
Response.Charset = "UTF-8";
Response.ContentEncoding = System.Text.Encoding.UTF8;
this.EnableViewState = false;
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
//this.ClearControls(MyDataGrid);
MyDataGrid.RenderControl(oHtmlTextWriter);
Response.Write(oStringWriter.ToString());
Response.End();
}

private void ClearControls(Control control)
{
for (int i=control.Controls.Count -1; i>=0; i--)
{
ClearControls(control.Controls[i]);
}

if (!(control is TableCell))
{
if (control.GetType().GetProperty("SelectedItem") != null)
{
LiteralControl literal = new LiteralControl();
control.Parent.Controls.Add(literal);
try
{
literal.Text = (string)control.GetType().GetProperty("SelectedItem").GetValue(control,null);
}
catch

{

}

control.Parent.Controls.Remove(control);
}

else

if (control.GetType().GetProperty("Text") != null)
{
LiteralControl literal = new LiteralControl();
control.Parent.Controls.Add(literal);
literal.Text = (string)control.GetType().GetProperty("Text").GetValue(control,null);
Response.Write(literal.Text);

control.Parent.Controls.Remove(control);
}
}
return;
}
void Item_Bound(Object sender, DataGridItemEventArgs e)
{
if (e.Item.ItemIndex >= 0)
{
e.Item.Cells[0].Text=Convert.ToString(e.Item.ItemIndex);
}
}   </script><body>   <form runat="server">

问题：1、转换EXCEL时TemplateColumn无值；2、中文乱码

解决方案 »

  1.   

    private void Button1_Click(object sender, System.EventArgs e)
    {
    //export to excelResponse.Clear();
    Response.AddHeader("Content-Disposition", "attachment; filename=myXls.xls");
    Response.ContentType = "application/vnd.ms-excel";this.EnableViewState = false;
    System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
    System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);MyDataGrid.RenderControl(oHtmlTextWriter);
    Response.Write(oStringWriter.ToString());
    Response.End();}

    TextBox导出时会为空，改用直接绑定<%# #>就ok了
