Hi,

I'm using GridGroupingControl 4.2 and I need to populate children of row on expand. The problem is that I don't know initially how many levels are in the hierarchy.

So what I need is:
1) initially fill the first level of rows (this is not a problem)
2) on expand of a row check whether there are children of the expanded row. if children exist add a new child table and populate it. This is a problem because I don't get the plus sign to expand when there are no children
3) for different rows the depths of hierarchy can be different, e.g. the first row might have 3 child tables while the second might have 10. The table structure for each sublevel is always the same.

Is there any way to achieve this? Do you have a sample for this?

Thanks in advance,

Christian

Hi Christian,

Thank you for your interest in Syncfusion products.

The child table can be loaded on demand if the child table is shown in the dropdown of the parent record.

Please refer the sample in the following link:
