ASPX:

ASP.NET

<asp:GridView runat="server"  ID="grd" OnRowDataBound ="grd_RowDataBound"  >
                <Columns>
                    <asp:TemplateField HeaderText="image">
                        <ItemTemplate>
                          <img src='<%# Eval("imagedata") %>' id="imageControl" runat="server" />
                        </ItemTemplate>   
                    </asp:TemplateField> 
                </Columns>
</asp:GridView>

CS:

C#

protected void grd_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if(e.Row.RowType==DataControlRowType.DataRow)
        {
            System.Web.UI.HtmlControls.HtmlImage imageControl = (System.Web.UI.HtmlControls.HtmlImage)e.Row.FindControl("imageControl");
            if (((DataRowView)e.Row.DataItem)["imagedata"] != DBNull.Value)
            {
                imageControl.Src = "data:image/png;base64," + Convert.ToBase64String((byte[])(((DataRowView)e.Row.DataItem))["imagedata"]);
            }
        }
    }

BC for VB:

<pre>If e.Row.RowType = DataControlRowType.DataRow Then
            Dim imageControl As System.Web.UI.HtmlControls.HtmlImage = CType(e.Row.FindControl("imageControl"), System.Web.UI.HtmlControls.HtmlImage)

            If (CType(e.Row.DataItem, DataRowView))("imagedata") IsNot DBNull.Value Then
                imageControl.Src = "data:image/png;base64," & Convert.ToBase64String(CType(((CType(e.Row.DataItem, DataRowView)))("imagedata"), Byte()))
            End If
        End If
