 DataGrid is really an old timer, in asp .net 2.0, Gridview is default data control. In the gridview you can always use hyperlink column as such

<asp:HyperLinkField DataNavigateUrlFields="LunWBT" DataNavigateUrlFormatString="files/{0}.doc" HeaderText="Download"  Text="This file" />

Parser Error

Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Parser Error Message: System.Web.UI.WebControls.DataGridColumnCollection must have items of type 'System.Web.UI.WebControls.DataGridColumn'. 'asp:HyperLinkField' is of type 'System.Web.UI.WebControls.HyperLinkField'.

I am getting this kind of error......... wat should i do now...??

Do you use gridview? If not, then you should.  

<asp:GridView ID="GridView1" runat="server" BackColor="White" BorderColor="White"
            BorderStyle="Ridge" BorderWidth="2px" CellPadding="3" CellSpacing="1" 

GridLines="None" AutoGenerateColumns="False">
            <FooterStyle BackColor="#C6C3C6" ForeColor="Black" />
            <RowStyle BackColor="#DEDFDE" ForeColor="Black" />
            <PagerStyle BackColor="#C6C3C6" ForeColor="Black" HorizontalAlign="Right" />
            <SelectedRowStyle BackColor="#9471DE" Font-Bold="True" ForeColor="White" />
            <HeaderStyle BackColor="#4A3C8C" Font-Bold="True" ForeColor="#E7E7FF" />
            <Columns>
                <asp:BoundField DataField="CategoryID" />
                <asp:HyperLinkField DataNavigateUrlFields="CategoryID"

 DataNavigateUrlFormatString="SmallWindow.aspx?id={0}"
                    DataTextField="CategoryName" NavigateUrl="SmallWindow.aspx" />
                <asp:BoundField DataField="Description" />
            </Columns>
        </asp:GridView>

Hi,

check this code

string strFilePath = folderPath + "\\" + GridView1.SelectedRow.Cells[0].Text;

FileStream sourceFile = new FileStream(@strFilePath, FileMode.OpenOrCreate);

long FileSize;

FileSize = sourceFile.Length;

byte[ getContent = new byte[(int)FileSize];

sourceFile.Read(getContent, 0, (int)sourceFile.Length);

sourceFile.Close();

Response.ContentType = sourceFile.ToString();

Response.AddHeader("content-disposition", "attachment;filename=" + GridView1.SelectedRow.Cells[0].Text + "");

Response.BinaryWrite(getContent);

Hope this will help you

Regards
