<DataGrid.Columns>
<DataGridTextColumn Binding="{Binding OrderId}" Header="OrderId" Width="*"/>
<DataGridTextColumn Binding="{Binding ProductId}" Width="*" Header="ProductId"/>
<DataGridTextColumn Binding="{Binding UnitPrice}" Width="*" Header="UnitPrice"/>
<DataGridTextColumn Binding="{Binding Quantity}" Width="*" Header="Quantity"/>
<DataGridTextColumn Binding="{Binding Discount}" Header="Discount"

this.dataGrid.AutoGeneratingColumn += dataGrid_AutoGeneratingColumn;
void dataGrid_AutoGeneratingColumn(object sender,
DataGridAutoGeneratingColumnEventArgs e)
{
e.Column.Width = new DataGridLength(1, DataGridLengthUnitType.Star);

One way to avoid is to set AutoGenerateColumnsto False(XAML only approach).
避免的一种方法是设置AutoGenerateColumns为False（仅 XAML 方法）。
Provide your own collection of columns and set width for last columnto *.
提供您自己的列集合并set width for last column到*.
<DataGrid x:Name="dataGrid" IsReadOnly="True" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Binding="{Binding OrderId}" Header="OrderId"/>
<DataGridTextColumn Binding="{Binding ProductId}" Header="ProductId"/>
<DataGridTextColumn Binding="{Binding UnitPrice}" Header="UnitPrice"/>
<DataGridTextColumn Binding="{Binding Quantity}" Header="Quantity"/>
<DataGridTextColumn Binding="{Binding Discount}" Header="Discount"
Width="*"/>
</DataGrid.Columns>
</DataGrid>
Replace bindings for your columns to corresponding properties in your model class. Output will be like this:
将列的绑定替换为模型类中的相应属性。输出将是这样的：
However, in case you want to distribute available space equally for all columns. You can set width to * for all columns. Output will be like this:
但是，如果您想为所有列平均分配可用空间。你可以set width to * for all columns。输出将是这样的：

I was fighting over this for some times now, the Width="\*"solved my problem while datagrid ColumnWidth="*"not working in my case.
我已经为此争论了一段时间，Width="\*"解决了我的问题，而 datagridColumnWidth="*"在我的情况下不起作用。

If you want to:
如果你想：
- keep AutoGenerateColumns="True" AND
- keep the columns Width being automatically adjusted to the data from the DataTable rather then have the same width
- 保持 AutoGenerateColumns="True" AND
- 保持列宽自动调整为来自 DataTable 的数据，而不是具有相同的宽度
you need to set "1*" to the last column only. Please:
您只需将“1*”设置为最后一列。请：
1) Add the event handler to .xaml
1) 将事件处理程序添加到 .xaml
2) Add the following code to .xaml.cs
2）在.xaml.cs中加入以下代码
private void dataGrid_AutoGeneratedColumns(object sender, EventArgs e)
{
int i = ((DataGrid)sender).Columns.Count;
DataGridColumn column = ((DataGrid)sender).Columns[i - 1];
column.Width = new DataGridLength(1, DataGridLengthUnitType.Star);
}

Add the attribute ColumnWidth="*" in the DataGrid object.
在 DataGrid 对象中添加属性 ColumnWidth="*"。
<Grid>
<DataGrid x:Name="datagridname" Margin="10" ItemsSource="{Binding}" IsReadOnly="True" ColumnWidth="*"/>
</Grid>

Well since its unused space, another way around will be use a weighted width rather than fixed one :
好吧，由于其未使用的空间，另一种方法将使用加权宽度而不是固定宽度：
<DataGrid x:Name="dataGrid" IsReadOnly="True" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Binding="{Binding OrderId}" Header="OrderId" Width="1*"/>
<DataGridTextColumn Binding="{Binding ProductId}" Header="ProductId" Width="1*"/>
<DataGridTextColumn Binding="{Binding UnitPrice}" Header="UnitPrice" Width="1*"/>
<DataGridTextColumn Binding="{Binding Quantity}" Header="Quantity" Width="1*"/>
