Text Extent - Resize DataGridView header cell's height

A

Ashutosh

Hi,
How can I find out the width in pixel that a particular text requires to
be drawn/written on a graphics object. (Similar to VC++ CDC::GetTextExtent)

I am displaying some data in DataGridView and the column headers are
vertical. So, I need to resize the header cell's height based on the max
space required to display the longest header text. This must be done at
runtime as there is no information of the data that will be displayed in
the grid.

I am using the following text to change the orientation of the displayed
text.

private void dataGridView1_CellPainting(object sender,
DataGridViewCellPaintingEventArgs e)
{
if (e.RowIndex == -1 && e.ColumnIndex >= 0)
{
e.PaintBackground(e.CellBounds, true);
e.Graphics.TranslateTransform(e.CellBounds.Left,
e.CellBounds.Bottom);
e.Graphics.RotateTransform(270);
e.Graphics.DrawString(e.FormattedValue.ToString(),
e.CellStyle.Font, Brushes.Black, 5, 5);
e.Graphics.ResetTransform();
e.Handled = true;
}
}


Thanks & Regards,
Ashutosh

Hello Ashutosh ,

Thank you for using Microsoft Managed Newsgroup Service, I'm Zhi-Xin Ye,
it's my pleasure to work with you on this issue.

You can call the Graphics.MeasureString() method to measure the size of the
column header text.

For example:

private void Form1_Load(object sender, EventArgs e)
{
//....... other code here.....

this.dataGridView1.ColumnHeadersHeightSizeMode =
DataGridViewColumnHeadersHeightSizeMode.EnableResizing;
float max = 0;
using (Graphics g = this.dataGridView1.CreateGraphics())
{
for (int j = 0; j < this.dataGridView1.ColumnCount; j++)
{
float w =
g.MeasureString(this.dataGridView1.Columns[j].HeaderText,

this.dataGridView1.ColumnHeadersDefaultCellStyle.Font).Width;

if (w > max)
{
max = w;
}
}
}

//Since you draw the header text at point(5,5), add 10 pixels
as padding.
this.dataGridView1.ColumnHeadersHeight = (int)max + 10;
}


For more information about the Graphics.MeasureString() method, you can
