Show Image From MSSQL binary image


Hi Guys,

I was struggling how to display image from MSSQL image column. One solution i found was to create a handler and then in the "Src" attribute set the path to handler and passing the file name. But this didn't solved my problem as i have a shared hosting and the server doesn't allows me to add a handler.

This gave me an idea to search the solution and I found the following solution. This is also applicable to MSSQL varbinary(max) column. Below is the code which is easy to understand.

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
           DataKeyNames="id" DataSourceID="SqlDataSource2" Width="169px">
            <Columns>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:Label ID="Label1" runat="server" Text='<%# Bind("id") %>'></asp:Label>
                    </ItemTemplate>
                </asp:TemplateField>
                 <asp:TemplateField>
                    <ItemTemplate>
                        <%--<%# System.Convert.ToBase64String((byte[])Eval("Picture"))%>--%>
                        <img width="100px" height="100px" src='data:image/png;base64,<%#System.Convert.ToBase64String((byte[])Eval("Picture"))%>' />
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>
        <asp:SqlDataSource ID="SqlDataSource1" runat="server"
            ConnectionString="<%$ ConnectionStrings:CheckImageConnectionString %>"
            SelectCommand="SELECT [ID], [Picture], [FullSnap] FROM [Emp]">
        </asp:SqlDataSource>
        <asp:SqlDataSource ID="SqlDataSource2" runat="server"
            ConnectionString="<%$ ConnectionStrings:lpuumsConnectionString %>"
            SelectCommand="select id,picture,fullsnap from employeepicture where id in (3,4,5)">
        </asp:SqlDataSource>

Thanks
Ritesh
