Bind List to DataGrid
提问by chrismasters
I have a problem binding a Listto a DataGridin WPF. Let me explain what I have tried.
我在 WPF 中将a 绑定List到 a 时遇到问题DataGrid。让我解释一下我的尝试。
public struct SomeInfo
{
public string Name;
public string Description;
public string ID;
}
List<SomeInfo> arrSomeInfo;
The arrSomeInfocontains multiple items of structure SomeInfo.
在arrSomeInfo包含结构的多个项目SomeInfo。
The DataGridLooks something like:
本DataGrid看起来是这样的：
<DataGrid Name="grdMailbag" AutoGenerateColumns="False" ItemsSource="{Binding}">
<DataGrid.Columns>
<DataGridTextColumn x:Name="cID" Binding="{Binding ID}" Header="ID" />
<DataGridTextColumn x:Name="cName" Binding="{Binding Name}" Header="Name" />
<DataGridTextColumn x:Name="cDescription" Binding="{Binding Description}" Header="Description" />
</DataGrid.Columns>
</DataGrid>
I have tried the following without success:
我尝试了以下但没有成功：
this.grdMailbag.ItemsSource = arrSomeInfo; //Didn't worked
this.grdMailbag.DataContext= arrSomeInfo; // Didn't worked
What is happening is that it is adding the rows as per List arrSomeInfobut all the rows are blank.
发生的事情是它正在添加行，List arrSomeInfo但所有行都是空白的。

Change this:
改变这个：
public struct SomeInfo
{
public string Name;
public string Description;
public string ID;
}
to this:
对此：
public class SomeInfo
{
public string Name {get;set;}
public string Description {get;set;}
public string ID {get;set;}
}
WPF does not support binding to fields. Only properties. And a structis not an appropiate type for the data you're trying to represent.
WPF 不支持绑定到字段。只有属性。并且 astruct不是您要表示的数据的合适类型。
