Loading Saved Grid Settings from XML file in XBAP deployed application

Emerson — Wed, 06 May 2009 18:34:09 GMT

I am attempting to use the SaveSettings and LoadSettings methods of the WPF grid version 3.1.

I have saved the XML document using the following code snippet:

Dim serializer As New XmlSerializer(GetType(SettingsRepository))

Dim baselocation As String = AppDomain.CurrentDomain.BaseDirectory

MSDataGrid.SaveUserSettings(CurrentSettings, UserSettings.All)

If File.Exists(baselocation & ADUserId & "_MSDataGrid_Settings.xml") Then

File.Delete(baselocation & ADUserId & "_MSDataGrid_Settings.xml")

End If

Using SaveStream As New FileStream(baselocation & ADUserId & "_MSDataGrid_Settings.xml", FileMode.CreateNew)

serializer.Serialize(SaveStream, CurrentSettings)

SaveStream.Close()

End Using

The problem is when I attempt to load the settings back into the application, the stream become a null value and causes an exception. Here is the code for loading.

Dim baselocation As String = AppDomain.CurrentDomain.BaseDirectory

If File.Exists(baselocation & ADUserId & "_MSDataGrid_Settings.xml") Then

' Loads the appropriate Xml settings file.

Dim serializer As XmlSerializer = New XmlSerializer(GetType(SettingsRepository))

Dim loadfilename As String = "/" & ADUserId & "_MSDataGrid_Settings.xml"

Dim this_stream As Stream = Application.GetResourceStream(New Uri("/" & ADUserId & "_TextStatusGrid_Settings.xml", UriKind.Relative)).Stream

settings = TryCast(serializer.Deserialize(this_stream), SettingsRepository)

' Change the current applied settings.

If Not settings Is Nothing Then

CurrentSettings = settings

If Not CurrentSettings Is Nothing Then

MSDataGrid.LoadUserSettings(CurrentSettings, UserSettings.All)

End If

this_stream.Close()

End If

This is a Full Trust deployed application. Code works fine when executing in VS 2008.

Thanks.

WPF Grid CheckBox behavior

Igor — Thu, 05 Mar 2009 13:09:12 GMT

Hi !

I have strange behavior of CheckBox columns of WPF Grid 3.1 (the latest version fron 17 February 2009).

There is small application, with TabControl of two tabs. The first tab control contains Xceed WPF grid control. The first column bind to some boolean variable. The problem occures then I check the CheckBox, than do not move to any other place in grid, just click on other tab item. When I return to the previous tab I see CheckBox still checked, but my variable restored to it's previous state. But if I'll move to another row of the grid after checking the checkbox everithing works fine.

My grid defined with UpdateSourceTrigger="CellContentChanged".

Please, help me to solve this problem.

Thanks!

Igor.
