确保文字环绕在一个DataGridView列 [英] Ensuring text wraps in a dataGridView column

问题描述

我的dataGridView与特定的列。当我写的dataGridView长文本它显示了我一个缩短版，用省略号，因为该列不够宽，能够显示整个字符串。

I have dataGridView with a particular column. When I write long text in dataGridView it shows me a shortened version, with ellipses, because the column isn't wide enough to display the entire string.

| textdsadasda...  |

什么我必须做的，如果我想的dataGridView显示在下一行这段文字，或自动换行？

What do I must to do if I want to dataGridView show this text in next line, or wrap the text?

| textdsadasda     |
| dasdasa          |  (continuation of line above)

如何才能做到这一点？

How can this be done?

可能是处理单元写生活动可以帮助你

May be handling cell painting event can help you

private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
    if (e.Value == null)
        return;
    var s = e.Graphics.MeasureString(e.Value.ToString(), dataGridView1.Font);
    if (s.Width > dataGridView1.Columns[e.ColumnIndex].Width)
    {
        using (
  Brush gridBrush = new SolidBrush(this.dataGridView1.GridColor),
  backColorBrush = new SolidBrush(e.CellStyle.BackColor))
        {
            e.Graphics.FillRectangle(backColorBrush, e.CellBounds);
            e.Graphics.DrawString(e.Value.ToString(), dataGridView1.Font, Brushes.Black, e.CellBounds,StringFormat.GenericDefault);
            dataGridView1.Rows[e.RowIndex].Height = (int)(s.Height * Math.Ceiling( s.Width / dataGridView1.Columns[e.ColumnIndex].Width)) ;
            e.Handled = true;
        }
    }
}
