Hi jsshivalik,

What's the requirement?

Do you want to  when click the filename, download the file?

If so, you could try the code below.

<asp:GridView ID="GridView1" runat="server"  AutoGenerateColumns="false">
            <Columns>
              <asp:TemplateField>
                  <ItemTemplate>
                      <asp:LinkButton ID="LinkButton1" runat="server" Text='<%#Eval("fileName") %>' OnClick="LinkButton1_Click"></asp:LinkButton>
                  </ItemTemplate>
              </asp:TemplateField>
            </Columns>
        </asp:GridView>

Code behind.

  protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                DataTable table = new DataTable();
                table.Columns.Add(new DataColumn("fileName"));
                table.Rows.Add("abc.pdf");
                table.Rows.Add("rep.pdf");
                GridView1.DataSource = table;
                GridView1.DataBind();
            }
        }

        protected void LinkButton1_Click(object sender, EventArgs e)
        {
            //if you want to get the filename , you could use the following two line of code 
            LinkButton button = sender as LinkButton;
            string filename = button.Text;



            Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.pdf");

            Response.Clear();
            Response.ContentType = "application/pdf";

            Response.WriteFile(Server.MapPath("/GridViewDemo/abc.pdf"));
            Response.End();
        }
