Title: Removing expand functionality from rows with no data in detail grid
Post by: joevernon on January 21, 2016, 08:14:30 pm

Hi

I load data into my grid remotely and populate nested grids for entries that have data under a certain field. However an empty nested grid is produced for a row that has no data under that field.

Is there a way to remove the expand functionality, including removing the expand icon, for rows that have no data in the nested grid?

I have tried calling 'rowInvalidate' on rows that have no items for their nested grid however this does not seem to work.

Thank Joe

Expand icon can be removed by column.render callback.

Code: [Select]

column.render = function ( ui ){
  if( there is no data in detail grid for current row i.e., ui.rowData ){
     return "";
  }
}

And beforeRowExpand event can be used to prevent default action of expansion of row by returning false.
