Dear David,
One of the ways to autoresize columns in datagrid is to
simulate the behavior of the mouse double click on the
column header border. This solution works perfect unless
you want to write the entire code to resize the columns.
Solution:
Create a control inherited from the DataGrid control and
create a public method with following signature and
implementation:
public void AutoSizeColumn(int colNumber)
{
// The rect1 will contain the bounds of the zeroth cell
at the specified column.
System.Drawing.Rectangle rect1 = this.GetCellBounds(0,
colNumber);
// Basically we need to extract the x and y information
so that the same can be passed
// to the base.OnMouseDown call to simulate the behavior
of double click over a column.
int X = rect1.X + rect1.Width;
int Y = rect1.Y - 5;
// 5 can be taken as a constant as above the cell at
zeroth row of this column will be the column header.
// The height of the column header must be greater than 5.
// For more precision, you can retrieve the header font /
header text and then use Graphics class's
// measurestring method to calculate the height of the
header and then pass y as somewhere
// in the middle of the header's Y + Height.
System.Windows.Forms.MouseEventArgs me = new
System.Windows.Forms.MouseEventArgs
(System.Windows.Forms.MouseButtons.Left, 2, X, Y, 0);
base.OnMouseDown(me);
}
Finally call this method from your client application and
pass the column id of the column you want to autoresize.
