  Hello,

  I have nested Datagrid in my application. (Parent → Child → Grand Child).
  
  When all the rows of all 3 Datagrids are expanded, I can see a vertical scrollbar. This scrollbar is applicable to only the ‘Parent’ grid. So, whenever I scroll down by using MouseWheel, it directly jumps to the next row of ‘Parent’ Datagrid.
  
  I would like to apply the scrollbar to apply all 3 Datagrids so that the scrolling via MouseWheel becomes smooth.

  Please help fix this scrollbar issue.

  Hi Swapnil,

  You can set C1DataGrid’s VerticalScrollStep property to set the scrolling steps in pixel values. Please refer to the following code for the same:

  datagrid.VerticalScrollStep = new DataGridScrollStep(20, DataGridScrollStepUnitType.Pixel);

  Kindly refer to the attached sample for the same. (See NestedDatagrid.zip)

  Thanks & Regards,
