  Hi team,

  I’m using check box in tree grid with @grapecity/wijmo.grid.selector

  When all of the sub elements are checked, I want to prevent the way the upper elements are checked.

  please provide solution for this issue.

  Thank you.

  Hi,

  This is the default behavior of the Selector to check the parent checkbox if all the child checkboxes are checked. Could you please explain more about your case that why you need to prevent this functionality, is it causing some issues in your application?

  Regards

  Thank you for your comment.

  I want to make a folder structure. I hope the empty folder will be maintained even if all of the descendants disappear.

  So is there any other way to solve this problem?

  If there are no child items in the dataSource for the parent row then treeGrid doesn’t remove the parent row it already maintains the folder structure and the parent row remains visible.

  For better understanding you may refer to the below sample, In the sample, first row doesn’t have child items but it is still visible.
