  Hi,

  What I would like to achieve here is to show tool tip text when Ellipsis is detected in the FlexGrid. Is this possible?

  Below attachment is the quick example from Microsoft Outlook:

  Hi.

  Thank you for your sample but it didn’t resolve my question.
  
  I have a better example here:
  
  

  The image above is C1FlexGrid with UseCompatibleTextRendering = True to achieve the Ellipsis effect.

  And now, I would like the tooltips to show the whole text when I mouse over it.
  
  Just like the Microsoft Outlook that I posted above.

  Is this possible to achieve?

  Hi Yap,

  To show the ellipsis in the cell you need to set the Trimming property CellStyle object to StringTrimming.EllipsisCharacter as given below:

  c1FlexGrid1.Styles.Normal.Trimming = StringTrimming.EllipsisCharacter;
  

  If you want to use the default Cell Label to show when there is an ellipsis sign in the cell then you just need to set the ShowCellLabels property of C1FlexGrid to true.

  If you want to show ToolTip when there is Ellipsis sign there in the cell then use the MouseMove event as given below:

   private void C1FlexGrid1_MouseMove(object sender, MouseEventArgs e)
          {
              HitTestInfo hitTestInfo = c1FlexGrid1.HitTest(e.X,e.Y);
              if (hitTestInfo.Type == HitTestTypeEnum.Cell)
              {
                  string measureString = c1FlexGrid1.GetDataDisplay(hitTestInfo.Row, hitTestInfo.Column).ToString();
                  SizeF stringSize = new SizeF();
                  Graphics g = c1FlexGrid1.CreateGraphics();
                  stringSize = g.MeasureString(measureString, c1FlexGrid1.Font);
                  if((stringSize.Width / c1FlexGrid1.Cols[hitTestInfo.Column].WidthDisplay) > 1)
                  {
                        toolTip1.Show(c1FlexGrid1[hitTestInfo.Row, hitTestInfo.Column].ToString(), c1FlexGrid1, hitTestInfo.X + 15, hitTestInfo.Y + 5);
                  }
                  else
                  {
                      toolTip1.Hide(c1FlexGrid1);
                  }              
              }        
          }
  
  

  Please find the attached sample demonstrating the same.
