Grid with tooltips scroll slow

[Rafael]

Hello,

I am trying to use tooltips in cell grids, because sometimes the content is too large. I followed this: https://ej2.syncfusion.com/angular/documentation/grid/how-to/custom-tool-tip-for-columns/ ... But I have some troubles:

The first is that:

But I solve changing the argument to any:

Then it works, but I got this problem because of content null:

So I changed the function to:

tooltip (args: any) {
  if (args.data[args.column.field] != null){
    let tooltip: Tooltip = new Tooltip({
      content: args.data[args.column.field].toString()
    }, args.cell);
  }
}

And it works exactly how I want:

But the pages has become slow... the scroll of page works lagging now... 

Do you know if there's something I can do to improve performance?

Hi Rafael, 

Greetings from Syncfusion support. 

Yes. From your requirement we can understand that you want to show tooltip for cell having large content. The suggested documentation demonstrates a way to create tooltip for each cell, which may affect the performance when the grid is having  more cells. 

We already have a built-in support for showing tooltip for large content, which can be defined by the columns.clipMode property as “EllipsisWithTooltip”. So you need not to use queryCellInfo event of this requirement. Please refer the below documentation for more information.
