Question

Help to display image from internet site,

Asked by: mathieu_cupryk

I have the following:
If there is no image in the database I have to use a default image.
    <EmptyItemTemplate>
    <asp:Image ID="Image2" runat="server" ImageUrl='~/Images/NoPhoto.jpg" />
    </EmptyItemTemplate>

Also how can I put male or female image.
<center>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="img_id"
    DataSourceID="SqlDataSource2">
    <Columns>
        <asp:BoundField DataField="img_title" HeaderText="img_title" SortExpression="img_title" />
        <asp:TemplateField HeaderText="Image">
            <ItemTemplate>
                <asp:Image ID="Image1" runat="server" ImageUrl='<%# "~/Handler.ashx?img_id=" + Eval("img_id") + "&" + "imagesize=F" %>' />%>'
            </ItemTemplate>
        </asp:TemplateField>
       
    </Columns>
    <EmptyItemTemplate>
    <asp:Image ID="Image2" runat="server" ImageUrl='~/Images/NoPhoto.jpg" />
    </EmptyItemTemplate>
</asp:GridView>

<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:dbaspnetConnectionString %>"
    SelectCommand="SELECT [img_id], [img_title], [img_stream]
              FROM [tbl_images] where img_is_primary = 1"></asp:SqlDataSource>
</center>

hi there,

one possible solution is to use the RowDatabound event and get the value returned from the object. You could then have an if statment to show an image based on what is returned.

   protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
    {
       
        //ImageContent='<%# Eval("ImageContent") %>'
        RbmBinaryImage DynamicImage = (RbmBinaryImage)e.Item.FindControl("RbmBinaryImage2");
        if (DynamicImage != null)
            DynamicImage.ImageContent = (byte[])((DataRowView)e.Item.DataItem).Row["ImageContent"];
       
    }

Can you help me.

hi there,
Let me get this straight. If you have no image in the database then you would like to display an image in it's place? But you need to display a male or female image depending on what ? Gender?
