[Solved] Automatic unchecked while scrolling radgrid with the checkbox in grid.

[Tushar]

Hi,
   I have a grid with one checkbox column. I have lot of records in the grid. If I check 2 or 3 checkboxes inside the grid check box column and do the scroll down, then previous checked cell value is unchecked. How can we remove this problem?  Please suggest it.

Thanks,
Tushar Shah.

Hi Tushar,

 When the virtualization is turned on (it is set like this by default), the visual elements will be recycled and then reused again. Consequently, you may get the behavior you experience - that some CheckBox-es are checked/unchecked upon scrolling. However, this will be observed only if no property from your business object is exposed as a data binding.

So, I would suggest you to expose a boolean property and bind it to your GridViewCheckBoxColumn by DataMemberBinding. If you want to enable/disable some of those check boxes, I would recommend you to use the IsReadOnlyBinding as illustrated in this article. 

Kind regards,
