Hi,

I'm not completely sure what is the exact issue you noticed in the mentioned online demo. If the problem on your side is that the controls are performing regular postback instead of Ajax request I'm not able to replicate this issue locally. Please see the movie from my local tests below and let me know if I'm missing something:

Hello,

By reloading I suppose you mean that the RadTreeList is updated. An actually this is expected as by checking the checkbox you are enabling the recursive selection for this control. In this case it is more than expected to have the RadTreeList updated but in this case this is done by ajax call and not with regular postback.

Hi i Am Using Rad Tree list To Enter the Persentage of Marks of students in department wise section wise and student wise.
 
While On page load i am binding all the data to the tree view data source but when the datasource is binded it is binding only parents initially and it is binding subsequest childs on needof datasource  and the previously entered data is erased everytime it  calls need of datasource event.
As i am binding all the data at page load i want to remove need of datasource event but it is throwing null exception.

I surfed almost all the examples available online all of them are being loaded ondemand....

Please help me on comming out of this issue..

Hello Kamasani,

I'm not sure that I understand your approach. Please note that mixing advanced data-binding and simple data-binding is not supported as it is mentioned in the following links:
TreeList / Simple vs Advanced Binding
Simple vs Advanced Binding

If this is not the case, please post the relevant code here so that I can get a better picture of your setup.

Best regards,
