Cell information

In order to get the cell’s information when hover the mouse on a cell, TableControlCellMouseHoverEnter event can be used and cell rectangle width and height of a cell can be retrieved RangeInfoToRectangle.

this.gridGroupingControl1.TableControlCellMouseHoverEnter += gridGroupingControl1_TableControlCellMouseHoverEnter;
void gridGroupingControl1_TableControlCellMouseHoverEnter(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCellMouseEventArgs e)
{
   Rectangle rectangle = new Rectangle();
   e.TableControl.CurrentCell.MoveTo(e.Inner.RowIndex, e.Inner.ColIndex);
   GridCurrentCell currentCell= e.TableControl.CurrentCell;
   if (e.Inner.ColIndex > 0)
   {
      rectangle =  e.TableControl.RangeInfoToRectangle(GridRangeInfo.Cell(e.Inner.RowIndex, e.Inner.ColIndex));
   }
   if (currentCell.Renderer != null)
   {
      String text = "Table:" + e.TableControl.TableDescriptor.Name +"\n"+ "Col Index: " +  e.Inner.ColIndex +"\n" + "cell bounds:" + rectangle + "\n" +"Cell Width:" + rectangle.Width +"\n" + "Cell Height:" + rectangle.Height +"\n" + "Col Text :" + currentCell.Renderer.ControlText"\n" +;
     GridTableControl tablecontrol = gridGroupingControl1.TableControl;
     tooltip1.SetToolTip(tablecontrol, text + "CellSize: " + cellSize);
     tooltip1.Active = true;
   }
}

tooltip1 = New ToolTip()
AddHandler Me.gridGroupingControl1.TableControlCellMouseHoverEnter, AddressOf gridGroupingControl1_TableControlCellMouseHoverEnter
Private Sub gridGroupingControl1_TableControlCellMouseHoverEnter(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCellMouseEventArgs)
   Dim rectangle As New Rectangle()
   e.TableControl.CurrentCell.MoveTo(e.Inner.RowIndex, e.Inner.ColIndex)
   Dim currentCell As GridCurrentCell = e.TableControl.CurrentCell
   If e.Inner.ColIndex > 0 Then
      rectangle =      Me.gridGroupingControl1.GetTableControl(e.TableControl.TableDescriptor.Name).RangeInfoToRectangle(GridRangeInfo.Cell(e.Inner.RowIndex, e.Inner.ColIndex))
   End If
    If currentCell.Renderer IsNot Nothing Then
       Dim text As String = "Table:" & e.TableControl.TableDescriptor.Name & "Col Index: " & e.Inner.ColIndex & "cell bounds:" & rectangle & "Cell Width:" & rectangle.Width & "Cell Height:" & rectangle.Height & "Col Text :" & currentCell.Renderer.ControlText
       Dim tablecontrol As GridTableControl = gridGroupingControl1.TableControl
       tooltip1.SetToolTip(tablecontrol, text)
       tooltip1.Active = True
    End If
End Sub
