Hi,

I have this ASPX file:
//DataGrid.aspx

<%@ Page language="c#" Codebehind="DataGrid.aspx.cs" AutoEventWireup="false" Inherits="DataControls.DataGrid" %>
<HTML>
        <HEAD>
                <title>DataGrid</title>
                <meta name="GENERATOR" Content="Microsoft Visual Studio 7.0">
                <meta name="CODE_LANGUAGE" Content="C#">
                <meta name="vs_defaultClientScript" content="JavaScript">
                <meta name="vs_targetSchema" content=" http://schemas.microsoft.com/intellisense/ie5">
        </HEAD>
        <body MS_POSITIONING="GridLayout">
                <form id="DataGrid" method="post" runat="server">              
                <asp:DataGrid id="DataGrid1" AutoGenerateColumns="False" style="Z-INDEX: 101; LEFT: 30px; POSITION: absolute; TOP: 21px" runat="server" BorderColor="Tan"       BorderWidth="1px" BackColor="LightGoldenrodYellow" CellPadding="2" GridLines="None" ForeColor="Black">
                                <SelectedItemStyle ForeColor="GhostWhite" BackColor="DarkSlateBlue"></SelectedItemStyle>
                                <AlternatingItemStyle BackColor="PaleGoldenrod"></AlternatingItemStyle>
                                <HeaderStyle Font-Bold="True" BackColor="Tan"></HeaderStyle>
                                <FooterStyle BackColor="Tan"></FooterStyle>
                                <PagerStyle HorizontalAlign="Center" ForeColor="DarkSlateBlue" BackColor="PaleGoldenrod"></PagerStyle>
                                <Columns>
                                        <asp:BoundColumn DataField="Title" HeaderText='<%= GetHeader("TILES") %>'>
                                        </asp:BoundColumn>
                                </Columns>
                        </asp:DataGrid>
                </form>
        </body>
</HTML>


and CODE-BEHIND:
//DataGrid.aspx.cs

namespace DataControls
{
        /// <summary>
        /// Summary description for DataGrid.
        /// </summary>
        public class DataGrid : System.Web.UI.Page
        {
                protected System.Web.UI.WebControls.DataGrid DataGrid1;
       
                private void Page_Load(object sender, System.EventArgs e)
                {
                        // DB is a Database wrapper to execute Stored Procedures
                        DB db = new DB();
                        // Setting the DataSource as GetAllData() is returning a DataSet 
                        DataGrid1.DataSource = db.GetAllData();
                        DataGrid1.DataBind();
                }

                public string GetHeader(String Text){
                        return Text;
                }

                #region Web Form Designer generated code
                        //Automated Code
                #endregion
        }
}


Now problem starts when I try to set the Header Text of BoundColumn in ASPX file like this: 

<asp:BoundColumn DataField="Title" HeaderText= '<%= GetHeader("TITLES") %>' >  </asp:BoundColumn> 

OR

<asp:BoundColumn DataField="Title" HeaderText= '<%  GetHeader("TITLES") ; %>' >  </asp:BoundColumn>  

I get nothing as Header Text But no error reported, and when I try to set it as DataBound Value like this:

<asp:BoundColumn DataField="Title" HeaderText= '<%# GetHeader("TITLES") %>' >  </asp:BoundColumn> 

I get error back that BoundColumn doesn't support DataBinding.

 

I don't understand how to do this, I could do it on runtime only in the code behind file but couldn't get any way to do it in ASPX file.

 

Any Pointers....

 

Thanks.

 

Rahul.
