Hi Telerik,
-------

In my application I am using telerik:GridViewImageColumn.
My scenario is I am assigning collection to gridview each object row contains the byte array of image. Collection contains more than 1000 rows. Actually collection is for my company product users. We have few products (say 10).
I am showing those product user details in gridview with product image. Each user row contains product image byte array.
After assigning data source when I scroll the gridview sometimes getting exception “Target invocation exception”Exception type: TargetInvocationException
Source: mscorlib

======== InnerException ========
Description: The value should not null.
Parametername: uriSource
Exception type: ArgumentNullException
Source: PresentationCore
Stack Trace:
System.Windows.Media.Imaging.BitmapImage..ctor(Uri uriSource, RequestCachePolicy uriCachePolicy)
Telerik.Windows.Controls.GridViewImageColumn.image_ImageFailed(Object sender,
ExceptionRoutedEventArgs e)
My xaml code for assigning data member is
<telerik:GridViewImageColumn Header="" UniqueName="colProductImage" DataMemberBinding="{Binding ProductImage}" ImageHeight="20" ImageWidth="20" />
What could be the solution for above problem?
My idea is to avoid above problem, instead of loading image byte data for each row just loads all 10 products data in
one collection and give the reference to image column with collection index. If it is possible please tell how to do .
Thanks for help.
