Hi Renato, 

Thanks for contacting Syncfusion Support. 

We are able to replicate the problem from your provided code example. In your provide code, you have bound ParentId with value “0” which leads to the reported problem. If you want to bind any record as parent, its value should be null to form parent-child hierarchy. 

 

Modified sample link:- https://www.syncfusion.com/downloads/support/forum/171194/ze/Serversample_(4)-1668379620 

Refer to the code below:- 

protected override void OnInitialized() 

    { 

        TreeData.Add(new BusinessObject() { LinhaId = 1, DataVenda = "Parent Task 1", ValorVenda = 10, ParentId = null  }); 

        TreeData.Add(new BusinessObject() { LinhaId = 2, DataVenda = "Child task 1", ValorVenda = 4, ParentId = 1}); 

        TreeData.Add(new BusinessObject() { LinhaId = 3, DataVenda = "Child Task 2", ValorVenda = 5, ParentId = 2}); 

      

       .   .   . 

}

Refer to the documentation Link and we have used the same in all of our documentations:-

Hi Renato, 

Query#:- to use the null Value and every time it returns this error  

As we have mentioned in previous update, we are unable to replicate the problem at our end. So share us the following details. 

1. NuGet package version details.
2. If possible replicate it in the above sample and revert us back.
3. Video demo to replicate the issue.
