Is it possible to prevent a multi line HeaderText in a DataGridView?

Question

When the length of the HeaderText property reaches a certain character limit and there is a space in the text, WinForms automatically inserts a link break in the he

Answer 1

You can not directly set it to false. The correct way of setting it to false is:

this.dataGridView1.ColumnHeadersDefaultCellStyle.WrapMode = DataGridViewTriState.False; 

Answer 2

if you want to stop multiline text in DataGridView control then Wrap Mode should be false and set padding

Answer 3

You could either set the ColumnHeadersDefaultCellStyle.WrapMode to DataGridViewTriState.False as the other answers already proposed

or

you could replace the spaces \s in your header string with non-breakable spaces \u00A0. The second solution has the benefit that you could set manual line breaks using \n in your header string and avoid auto wrapping. E.g.:

+----------------------------------------------+
| A\u00A0very\u00A0long\u00A0first\u00A0Line\n |
| A\u00A0second\u00A0very\u00A0long\u00A0line  |
+----------------------------------------------+

The first solution is not allowing manual line breaks (everything is one line).

Answer 4

The ColumnHeadersDefaultCellStyle property of the DataGridView has a boolean property called WrapMode. This is true by default. Make it false to set the required behaviour.
