Hi,

The example on the website on how to use GridBinaryImageColumn to update an image in a radgrid does not have a "codebehind" equivalent. Would it be possible to post a simple example how to implement a "RadGrid1_UpdateCommand" where the changed image is stored? 

Thanks Peter

Hello Peter,

You can examine the implementation presented on the following online demo of RadListView for ASP.NET AJAX:
http://demos.telerik.com/aspnet-ajax/listview/examples/firstlook/defaultcs.aspx

Part of it represents how to save the binary array from RadBinaryImage manually in code-behind and propagate the changes in the data source.

I have applied the code from this example to a radgrid I am using with a GridBinaryImageColumn but when I try to edit/update a record that has no image (or insert) the upload control reports a file count=1 but the length of the stream is either 0 or 1 - basically no file. Any idea what we are doing wrong? The uploaded file's name is reported correctly by the upload control which is curious. Thanks.

Hello Karl,

This is indeed a strange issue since the upload control should indicate one file (if uploaded) and the stream should be non-empty. In order to investigate the case, I suggest you prepare a simplified working version of your project (with data source included) and send it enclosed to a regular support ticket. We will examine it locally and will get back to you with our findings.

Kind regards,
