Hello Marc,

Please let me know if you need any further assistance with this matter.

Hello Marc,

Here is a sample which modifies the data when assigning it to the grid data source http://jsfiddle.net/w4ehc9r4/3/

It is not modifying the data and it makes the correct structure which the hierarchical grid expects.

Hello vasya,

this is not an acceptable solution for me because i am forced to use this datasource format in the project i am working on

Why is it that the second grid would take the correct "responceDataKey" while the third grid won't

Thank you for your help

Hello Marc,

Thank you for getting back to me.

I modified you data source a bit since it was not in the correct format and this sample is working as expected. I am attaching your modified sample for your reference.

Please have a look at this sample and let me know if you have any additional questions afterwards.

Hello Vasya,

I did not see a difference in the code you updated. The code is the same in the two samples. i put the column layout of the third grid inside the column layout of second grid just like you said.

Also, the problem i told you about was not solved in your sample

if you look carefully, the third grid's content is "level 1", while it should be "level 2" as specified in the data

it seems as if the third grid is taking the datasource of the second grid

Thank you for your help
