    Hi,
    I have data where the first row is not expandable or doesn’t have any children, in this case tree grid doesn’t render the data. But, when my first record is expandable or does have children it works fine. Can you explain me why is this unusual behaviour happening. Since, I can’t put my data. I have provided a sample data. This data has no child for the first row and only the second row has children. Treegrid doesn’t bind for this data. Please let me know whether I am missing any thing.

    Hello MohanV,

    Yes. You could set first element without any children.
    Please take a look this example: http://jsfiddle.net/txhi/qdx4bxt2/
