[英]Change DataGrid Column display value in AutoGeneratingColumn
I have dataGrid.ItemsSource
bound to a list of EntityItem, Client
, that containt another EntityItem, Company
. 我有dataGrid.ItemsSource
绑定到EntityItem, Client
的列表,该列表包含另一个EntityItem, Company
。
When my dataGrid
is displayed, in my Company
Column, I have the type of my object ( System.Data.Entity.
...) I would like instead to display my Company.Name
. 当显示我的dataGrid
,在“ Company
列中,我具有对象的类型( System.Data.Entity.
。...),而我想显示我的Company.Name
。
In WindowsForm I could just do : 在WindowsForm中,我可以做:
e.Value = ((Company)(dgv["Company", e.RowIndex].Value)).Name;
But I can't find a way to do in properly in WPF. 但是我找不到在WPF中正确执行操作的方法。
For now I have : 现在我有:
private void dataGridUsers_AutoGeneratingColumn_1(object sender, DataGridAutoGeneratingColumnEventArgs e)
{
DataGrid dgv = (DataGrid)sender;
if (e.PropertyName == "Company")
{
if (e.PropertyType == typeof(Company))
{
...
}
}
}
So I can make sure I'm on the right column, but now I'm stuck, I don't know how to change the way I want the column to display the data ... I tried to look into e.PropertyDescriptor
but it's only to Get the properties. 所以我可以确保我在正确的列上,但是现在我被卡住了,我不知道如何更改我希望该列显示数据的方式...我试图查看e.PropertyDescriptor
但是只是获取属性。
DataGridAutoGeneratingColumnEventArgs
object has Column
property which contains a generated DataGridColumn
instance. DataGridAutoGeneratingColumnEventArgs
对象具有Column
属性,该属性包含一个生成的DataGridColumn
实例。 Concrete type is DataGridTextColumn
, which has Binding
property. 具体类型为DataGridTextColumn
,它具有Binding
属性。
You can change binding path to work with Column.Name
property 您可以更改绑定路径以使用Column.Name
属性
private void DataGridOnAutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
{
if (e.PropertyName == "Company")
{
var c = (DataGridTextColumn)e.Column;
var b = (Binding)c.Binding;
b.Path = new PropertyPath("Company.Name");
}
}
