没有找到更好的办法，只能重写GridViewColumn。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Controls;
using System.Windows;
namespace Smart.Client.MD_BaseControl
{
/// <summary>
/// 不允许改变列宽的GridViewColumn
/// </summary>
public class xFixedWidthGridViewColumn : GridViewColumn
{
#region Constructor
static xFixedWidthGridViewColumn()
{
WidthProperty.OverrideMetadata(typeof(xFixedWidthGridViewColumn),
new FrameworkPropertyMetadata(null, new CoerceValueCallback(OnCoerceWidth)));
}
private static object OnCoerceWidth(DependencyObject o, object baseValue)
{
xFixedWidthGridViewColumn fwc = o as xFixedWidthGridViewColumn;
if (fwc != null)
return fwc.FixedWidth;
return 0.0;
}
#endregion
#region FixedWidth
public double FixedWidth
{
get { return (double)GetValue(FixedWidthProperty); }
set { SetValue(FixedWidthProperty, value); }
}
public static readonly DependencyProperty FixedWidthProperty =
DependencyProperty.Register("FixedWidth", typeof(double), typeof(xFixedWidthGridViewColumn),
new FrameworkPropertyMetadata(double.NaN, new PropertyChangedCallback(OnFixedWidthChanged)));
private static void OnFixedWidthChanged(DependencyObject o, DependencyPropertyChangedEventArgs e)
{
xFixedWidthGridViewColumn fwc = o as xFixedWidthGridViewColumn;
if (fwc != null)
fwc.CoerceValue(WidthProperty);
}
#endregion
}
}
<GridView xmlns:l="clr-namespace:FixedWidthColumnSample">
<l:FixedWidthColumnHeader="Coerce Fixed-Width Column"
DisplayMemberBinding="{Binding Name}"
FixedWidth="100"/>
</GridView>

试试其它关键字

　ListView
