Grid PDF Export and Binary Image

[ihsan]

hi telerik,

i have a grid with one row and one column. this column has a html data.. tables, images and etc..
but one of the image comes from database ( for security reasons )
when i open grid, i can see image in grid but when i want to pdf export there is an error about this image path..
System.Web.HttpException: '/async/display.ashx?id=1043' is not a valid virtual path.

as you can see '/async/display.ashx?id=1043'  streams image from db.

sample code;

<telerik:RadGrid ID="grvSchedules" runat="server" Width="100%" CssClass="GridVClass"
        AutoGenerateColumns="False" AllowPaging="True" GridLines="None" PagerStyle-AlwaysVisible="false"

        OnNeedDataSource="grvSchedule_NeedDataSource" OnItemCreated="grvSchedule_ItemCreated"
        HorizontalAlign="Left">
        <ExportSettings IgnorePaging="true" ExportOnlyData="true">
            <Pdf PageHeight="297mm" PageWidth="210mm" PageTitle="Client Schedule" />
        </ExportSettings>
        <PagerStyle Mode="NumericPages" AlwaysVisible="False"></PagerStyle>
        <MasterTableView Width="100%" DataKeyNames="RecId" CellSpacing="1" PageSize="20">
            <Columns>

thanks for your help..

I doubt this will work directly given the fact that the documentation states that the absolute path is a must.

Hello Ihsan,

Please use an absolute path as suggested by Diego - otherwise the PDF engine won't be able to resolve the image.
