DataGridView with Wrap text in Cell but without newline

Question

hi experts ,

I am trying to wrap the long text in my datagridview cell by using the

 dataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.None;
            dataGridView1.DefaultCellStyle.WrapMode = DataGridViewTriState.True;

but what it does is , it creates a newline in the cell itself to fill the rest of the text . i just want it to adjust all the text inside it according to the width of cell but should not create a new line or increase the height or width of the cell .

Answer 1

In the following code, there are two columns, the second after pasting text into it and leaving text will wrap.

dataGridView1.DefaultCellStyle.WrapMode = DataGridViewTriState.True;
dataGridView1.Columns[1].AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
dataGridView1.Columns[1].DefaultCellStyle.WrapMode = DataGridViewTriState.True;
dataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.AllCells;

Can not help but should not increase the height or width of the cell .

Part that draws the DataGridViewTextBoxCell.

The text drawing is below.

Click on a method to see how it works. Copy these to get the values of formattedString, valBounds, and flags.

Size tmpSize = new Size(valBounds.Width, 1);
Size size = TextRenderer.MeasureText(graphics, formattedString, font, tmpSize, flags);

Executing will determine the size required to draw the text. Adjust the Font size so that this size is no larger than valBounds.Size.

Just do your best with your own strength. I wish you good luck. ​
