Hi Andrzej,

I have tested your scenario using WebGrid build 401 and Framework build 751. Unfortunately, they working fine as seen in the video attachment named ClientBindingSettingDesigner.rar. Have you applied for WebGrid's latest hotfix? The latest hotfix of WebGrid that has been released is 402. You can update it by using UpdateManager.

And also please notes that if the choosen is the default option, it won't show up in html code (e.g 'Reuse server datasource assigned in either DataSourceID or DataSource property'). Thank you.

Regards,

Julia

it's working ok

My ver: WebGrid build 401 and Framework build 751

Hi Andrzej,

Could you try using the latest build of WebGrid (402)? It is recommended to use the latest build. If the issue still persist, please let me know.

Regards,

Julia
