列表框不显示displaymember

Question

I have a ListBox , and it has a Binding to dtAtt , but when I run the app, the ListBox show the items with empty content.

Code:

Xaml:

<Expander Name="expandAtt" Header="Attachment">
    <ListBox x:Name="lstAtt" MouseDoubleClick="lstAtt_MouseDoubleClick" ItemsSource="{Binding}" DisplayMemberPath="Name">
    </ListBox>
</Expander>

C#:

    public DataTable  dtAtt;

    string sql = "SELECT Name FROM Item2Inv_Link";
    dtAtt = DataBase.GetTable(sql);
    lstAtt.ItemsSource = dtAtt.Select("Att_Pkg=0");

Answer 1

You need to change your your source you're binding in the code just a bit. Try this:

lstAtt.ItemsSource = dtAtt.Select("Att_Pkg=0").CopyToDataTable().DefaultView;
