How to disable validation on BinaryImage on item edit in Grid

[Owidat]

Hi,

I want to display image in my grid and I'm following this demo "BinaryImage / Binary Images and Upload in Grid", I need to disable validation while editing, I'm not able to reach GridBinaryImageColumn, I need this because clients my try to update ImageName or Description only but validation control not allowing this ..

any ideas how to do that?

Hello Owidat,

To achieve your goal you can check if there is any file uploaded with the updated item, when RadGrid is updating. If no file was uploaded, you can skip modifying the data field holding the binary image data.

However, I am sending you a sample test page which demonstares the needed functionality.

All the best,

Dear Pavlina
Your solution just work fine for me but there is one issue. I need to keep validation for insertion only and disable it for editing only. Can you suggest solution?? I think we have to keep validation enabled as mentioned in original code and disable it when we press edit button. A sample code or hint for this scenario will help me resolve my problem.
