GridView绑定DataTable如何添加FileUpload控件？
想添加一个string是这样protected void CreateFilestable()
{
//实例化数据表
this.FilesTable = new DataTable();
//组建文件名数据列
DataColumn fileNameCol = new DataColumn("FileUpload", typeof(string));
this.FilesTable.Columns.Add(fileNameCol);
}
protected void Button1_Click(object sender, EventArgs e)
{
DataRow row = this.FilesTable.NewRow();
row["FileUpload"] = "abc";
//将数据行添加到数据表中
this.FilesTable.Rows.Add(row);
//数据表接受一切修改
this.FilesTable.AcceptChanges();
GridView1.DataSource = FilesTable;
GridView1.DataBind();
}
我把DataColumn fileNameCol = new DataColumn("FileUpload", typeof(string));改成
DataColumn fileNameCol = new DataColumn("FileUpload", typeof(FileUpload));
row["FileUpload"] = "abc";
改成
row["FileUpload"] = new FileUpload();
运行时候，会出错，说FilesTable不是有效的数据源
--------------------编程问答-------------------- 可以使用模板列来实现：
<asp:GridView ID="GridView1" runat="server">
<Columns>
<asp:TemplateField>
<asp:FileUpload runat="server" ID="compFile"></asp:FileUpload>
</asp:TemplateField>
</Columns>
</asp:GridView>
--------------------编程问答-------------------- 罪过，打错了，更正下:
--------------------编程问答--------------------
<asp:GridView ID="GridView1" runat="server" onrowupdated="GridView1_RowUpdated">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:FileUpload runat="server" ID="compFile"></asp:FileUpload>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
我是用DataTable绑定的，DataTable那边怎么写 --------------------编程问答-------------------- 直接在模板列中设置
<asp:TemplateField>
<ItemTemplate>
<asp:FileUpload runat="server" ID="FileUpload 1"></asp:FileUpload>
</ItemTemplate>
</asp:TemplateField>
findcontrol查找控件
补充：.NET技术 , ASP.NET
