HI,
Can I disallow the user to resize Columns' width in a datagrid ?
I fixed the width in the TableStyles.

Try to hide header row:- DataGrid.RowHeadersVisible = false.

Write a DataGrid MouseUp event for ColumnResize and RowResize
Try the code below.

private void dataGrid1_MouseUp(object sender, MouseEventArgs e)
{
DataGrid myGrid=(DataGrid)sender;
DataGrid.HitTestInfo myHitInfo = myGrid.HitTest(e.X,e.Y);

if(myHitInfo.Type == DataGrid.HitTestType.ColumnResize)
{
//Do Nothing
}
}

Hope this helps,
Cheers,
Arun.

Well, this solution is a bit complicated than just remove header row
though it works either with a small correction:- instead of handle
MouseUp event you have to write new class that derived from DataGrid,
*override* method OnMouseDown then suppress base implementation for
ColumnResize types. For more information see [1]. Here you are C#
implementation:

public class DataGridWithFixedColumnWidth : DataGrid
{
protected override void OnMouseDown(MouseEventArgs e)
{
DataGrid.HitTestInfo hitInfo = HitTest(e.X, e.Y);
// suppress ColumnResize event
if (hitInfo.Type == DataGrid.HitTestType.ColumnResize) return;

base.OnMouseDown (e);
}
}

Thankx guys, I'll try both solutions..

a question about HitTestInfo :

can i use this property to disallow a user to select a row in a datagrid
?
here's the problem:
In a datagrid that is used only in view mode,I don't want the user to be
able to change the row selections. For this purpose, I disabled the
datagrid, but the disadvantage of this method is that it prevents the
user to scroll the datagrid, and thus can't see all the records.

Yes there are 8 HitTestType below is the list,
Best way is to write a class as mentioned by Sergey to disable the
datagrid.

DataGrid.HitTestType.Cell
DataGrid.HitTestType.Caption
DataGrid.HitTestType.ColumnHeader
DataGrid.HitTestType.ColumnResize
DataGrid.HitTestType.ParentRows
DataGrid.HitTestType.RowHeader
DataGrid.HitTestType.RowResize
DataGrid.HitTestType.None

block all the HitTestType each with separate condition
Hope this helps,
