Hi Ash,

Thanks for contacting Syncfusion forum.

Query: When I click on 1st row check box it randomly select another checkbox.

Based on your shared sample, we could see that you are using the checkbox column feature with frozen row property of the treegrid. Currently, we don’t have support for frozen rows with checkbox column feature of the treegrid. And currently we don't have any plan to implement this feature.

Kindly get back to us for further assistance.
