I have written the code like this....

DataTable dt = new DataTable();
dt.Columns.Add("Image", typeof(string));
DataRow dr;
int i = 1;
foreach (string file in Directory.GetFiles(Server.MapPath(@"ImageUpload\")))
{
  //string nm = Path.GetFileName(file);
  dr = dt.NewRow();
  dr[0] = ResolveUrl(file);
  dt.Rows.Add(dr);
  i += 1;
}
grdimage.DataSource = dt;
grdimage.DataBind();

Here, my problem is, that the image is not displayed in grid view. Can anyone please help me out?

check this.

DataTable dt = new DataTable();
        dt.Columns.Add(new DataColumn("Image", typeof(string)));
        DataRow dr;
        int i = 0;
        foreach (string file in Directory.GetFiles(Server.MapPath(@"ImageUpload\")))
        {
            dr = dt.NewRow();
            dt.Rows.Add(dr);
            dr["Image"] = "ImageUpload/" + System.IO.Path.GetFileName(file);
            i += 1;
        }
        GridView1.DataSource = dt;
        GridView1.DataBind();

XML

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
      <Columns>
          <asp:ImageField  DataImageUrlField="Image">
          </asp:ImageField>
      </Columns>
  </asp:GridView>

Just because you have an image path doesn't mean it will automatically display the image, you need to do a little work.

You have a template column that includes an Image control and you bind the src property to the Image column from your DataTable
