Resize font if text doesnt fit into cell (XRTable)

Question

How to resize cell content (font size) if it doesn't fit. I don't want word-wrap or change cell's size since the form has to fit on single page. The text might have various lengths. It might contain spaces but doesn't have to.

@edit

I've made a mistake. The control I meant is not a XtraGrid but XRTable.

Reading their documentation, couldnt really find anything usefull. I can probably calculate the text height and width by hand. However, I'm asking if there's some kind of way foreseen by devexpress itself. — user2475983, Jan 19 '16 at 11:41
I'm assuming you're using System Drawing somewhere? If so, try using this https://msdn.microsoft.com/en-us/library/6xe5hazb%28v=vs.110%29.aspx and looping through font sizes to find the one that works best for your area? — Zach Ross-Clyne, Jan 19 '16 at 12:01
@Majkl Your solution might work, I didn't have time to check it yet, gonna update immediately when I do so. — user2475983, Jan 20 '16 at 12:15

I suggest you to look at the Appearances at first. There are multiple ways to customize appearances of individual rows and cells.

If these options are not helpful, you can manually draw cell content as you needed using the Custom Drawing feature. For example, you can use the GridView.CustomDrawCell event to check whether or not the cell's content is exceed the cell's bounds and update the font of this cell accordingly.

You can change the font of the cell where the text flows as follows

private void gvView_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
    {
      if (e.Column != null && e.Column.Name == bgcStav.Name)
      {
        float minFontSize = 6;
        string text = "teeeeeeeeeeeeeext";
        int minWidth = gvView.CalcColumnBestWidth(bgcStav);        
        SizeF s = e.Appearance.CalcTextSize(e.Graphics, text, minWidth);
        if (s.Width >= minWidth)
        {
          e.Appearance.Font = new Font(e.Appearance.Font.FontFamily, minFontSize);          
        }
      }
    }

but it is much better to trim the text if it overflows (you do not know how long the text can be), when you do not want to use wordwrap

 private void gvView_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
    {
      if (e.Column != null && e.Column.Name == bgcStav.Name)
      {
        string text = e.DisplayText;
        string newText = "";
        int maxWidth = e.Bounds.Width - 20;
        SizeF textSize =e.Graphics.MeasureString(text, e.Appearance.Font);
        if (textSize.Width >= maxWidth)
        {
          string textPom = "";
          for (int i = 0; i < text.Length; i++)
          {
            textPom = text.Substring(0, i) + "...";
            textSize = e.Graphics.MeasureString(textPom, e.Appearance.Font);
            if (textSize.Width >= maxWidth)
            {
              newText = text.Substring(0, i - 1) + "...";
              break;
            }
          }
          e.DisplayText = newText;
        }           
      }
    }

Advantage of this solution is that the crop only what is displaied, but in the datatable text remains in its original form

Sorry for late reply, Your solution would work on `XtraGrid`, but I've made mistake in my question. Please see the update. — user2475983, Jan 25 '16 at 16:24
