How to wrap text without spaces in DataGridView

How can we wrap text without spaces in DataGridView?

I set DataGridView.DefaultCellStyle.WrapMode = DataGridViewTriState.True.

But WrapMode does not wrap columns with a single word without spaces.

How can we word break along with WrapMode?

Simply add the following line after DataBinding:

DGLogs.Columns[0].DefaultCellStyle.WrapMode=DataGridViewTriState.True;

set
AutosizecolumnMode=AllCells
AutosizeRowMode=AllCells

in Property windows

The output will be as shown in the below image:

You can play with the CellPainting event.

The DrawString respects the bounding Rectangle and wraps wherever it hits the right boundary.

You can uncomment the condition to apply only to cells which go over a limit you set. For best control you would have to measure the length of the FormattedValue to find out the exact limit.

You may also want to fine-tune the draw position, if you have special alignments in your cells.

private void DGV1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
    if (e.Value == null) return;
    if (e.FormattedValue.GetType() != typeof( System.String) ) return;
    bool selected = (e.State & DataGridViewElementStates.Selected) 
                            == DataGridViewElementStates.Selected;
    string s = e.FormattedValue.ToString();

    //if (s.Length > 20) // Apply to all or only those breaking your limits
    {
        e.PaintBackground(e.CellBounds, selected);
        e.Graphics.DrawString(s, DGV1.Font, selected ? 
                   SystemBrushes.HighlightText : SystemBrushes.ControlText, 
                   new Rectangle(e.CellBounds.X + 1, e.CellBounds.Y + 2, 
                                 e.CellBounds.Width - 2, e.CellBounds.Height - 4));
        e.Handled = true;
    }
}

Setting the Row.Heights is up to you. If you go for measuring the FormattedValue you will get a RectangleF back; so you'll also know the necessary Height for that Cell. Comparing it to the current Row.Height you could gradually adapt it for each Row, i.e. make it larger each time it is necessary.. I didn't include, because it will result in Rows with varying Heights and that may be unwanted/unnecessary in your case. If you're interested, I can post the code, though..
