WPF toolkit DataGrid show fields even with browsable attribute set to false

由 ぃ、小莉子 提交于 2019-12-30 04:30:21
问题 Hi have an observable collection that I bind to a DataGrid using the itemsource property of the DataGrid. All the properties of the class inside the collection are displayed properly in the DataGrid. Now, I want to hide some fields to the DataGrid using the browsable attribute [Browsable(false)] in the class. It works well in winforms, but it seems not working in WPF. Someone knows why? I can hide the columns later, but I don't want to loss performance in this way. Is there any other solution

Django REST Framework: slow browsable UI because of large related table

由 旧巷老猫 提交于 2019-12-22 04:33:09
问题 I have a model in my API that has a foreign key to a table with tens of thousands of records. When I browse to that model's detail page in the browsable UI, the page load takes forever because it is trying to populate the foreign key dropdown with tens of thousands of entries for the HTML form for the PUT command. Is there anyway to work around this? I think my best solution would be to have the browsable UI not show this field and thus prevent the slow load. People can still update the field

Conditional “Browsable” Attribute

由 烈酒焚心 提交于 2019-12-17 09:50:03
问题 Is there a way to make a "Browsable" attribute conditional, so the property that applies it will sometimes appear in the properties page and sometimes not? thanks :) 回答1: There is no easy way. You can possibly work this out by implementing ICustomTypeDescriptor. Here is a good article about implementing ICustomTypeDescriptor. Or you can associate your own ControlDesigner with your class and override the PreFilterProperties method to add or remove properties viewed in the property grid.

问题 I've written a custom ComboBox control that inherits from System.Windows.Forms.ComboBox. It has a "Value" property that I've written as follows: Public Property Value() As Object Get If SelectedIndex = -1 Then Return Nothing If String.IsNullOrWhitespace(ValueMember) Then Return Items(SelectedIndex) Else Return FilterItemOnProperty(Items(SelectedIndex), ValueMember) End If End Get Set(ByVal newvalue As Object) '... End Set End Property Basically, reading the Value will return Nothing if

Making the Visual Studio designer ignore a public property

问题 I have a UserControl with a public property using the following attributes: [Browsable(false)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)] I have tried deleting the owner form, re-creating a fresh form in Visual Studio 2010, and adding this UserControl to the form.

问题 Are there different steps to register an Android Activity as a BROWSABLE intent on Android 2.3 (API level 10) and earlier versions?
