SfDataGrid With tooltips over nested headers

Question

I have been trying to use custom tool tips for the SfDatagrid, and unfortunately none of the approaches Ive used have worked perfectly. In each of the methods, the tooltips posititioning is quite far off from where it should be positioned when showin on nested sub tables. Or when using the SFToolTip, the positioning is better, but it never hides when the mouse moves. Each of the columns that has a tool tip has ShowHeaderToolTip = true.

Method 1:

grid.ToolTipOpening += grid_ToolTipOpening;
subGrid.ToolTipOpening += grid_ToolTipOpening;


private void Grid_ToolTipOpening(object sender, Syncfusion.WinForms.DataGrid.Events.ToolTipOpeningEventArgs e)
{
var tt = string.Empty;
var grid = (SfDataGrid)sender;


switch (e.Column.MappingName.ToLower())
{
case "mapping1":
tt = "Lorem ipsum dolor sit amet.";
break;
case "mapping2":
tt = "Duis aute irure dolor in reprehenderit.";
break;
default:
break;
}
e.ToolTipInfo.Items[0].Text = tt;
}

Problem: The tooltip works fine on the main header row, but for any nested rows, the positioning is WAY off.

Method 2: Used the same code, but utilized a SFToolTip with _tooltip.Show(tt);

Problem: The positioning was much better, but the tooltip would hang around for a long time even after the mouse moved away.

Method 3: Attempted to use the built in winforms tooltip.

Problem: The built in tooltip requires a Control type parameter, which was not accessible from the SF header control.

I liked method 1 the best as the tool tip would disappear on mouse move, and it provided the same look and feel as the SFtoolTip. However, would you guys be able to fix the positioning issue? Or let me know how to accomplish what I am trying to do.

No worries, if you use the example i provided and look at any of the tooltips in the nested sub grid column headers you will see the issues.
