如何将dataSource绑定到组合框？

Question

I am trying to bind data with combobox but couldn't bind it.

CBFolders.ItemsSource = client.GetNewsLetterFoldersAsync("token", 12, 3427).AsDataView();

In this code I am using web service which method GetNewsLetterFolders return data table.

Please help me how I can bind this??

Answer 1

Return type of web service method should be a model class. If it's returning folderId & Description and both properties should member of FolderData class. Hence FolderData essentialy become table.

I consider service method GetNewsLetterFoldersAsync returns List. So combox box should be bind like this

CBFolders.ItemsSource = await client.GetNewsLetterFoldersAsync("token", 12, 3427);

<ComboBox x:Name="CBFolders" SelectedValuePath="folderId" DisplayMemberPath="Description" />

SelectedValuePath should be bind with that property which is needed while selection changes in ComboBox . DisplayMemberPath should be bind with that property which is needed to show in ComboBox .

CBFolders.SelectedItem will return selected folderId

You need to convert the datatable to List when you are binding it to ItemsSOurce property. CBFolders.ItemsSource = client.GetNewsLetterFoldersAsync("token", 12, 3427).GetList(). Hope this helps.
