从DataTable到DataGridView的字符串：“ \\ n”不解释为换行

Question

I have DataTable which contains some strings with "\\n" signs. I need to take those strings and put them into DataGridView cells. "\\n" should be interpreted as new line.

What I am doing:

dataGridView1.Rows[1].Cells["actionColumn"].Value = subStepLine["action"].ToString();

where subStepLine["action"] is cell in DataTable with string inside "firstLine\\n\\nsecondLine"

I want to show it in DataGridView as:

"firstLine

secondLine"

but it shows as: "firstLine\\n\\nsecondLine".

On the other hand, when I am doing is like this:

dataGridView1.Rows[1].Cells["actionColumn"].Value = "firstLine\n\nsecondLine"

then it is fine and '\\n\\n' are treated as new lines.

I have wrapMode set on true.

Should I set something in DataTable too?

If more code needed I can add it, just dont wanted to do my post unredadable

Answer 1

If I understood correctly, you wish to have a single cell to display a multi line text, if so, try replacing the \\n literals with Environment.NewLine() (that will resolve to \\r\\n).

This also seems like a duplicate: C#: multiline text in DataGridView control
