Hello all,
I'm fairly new to WPF, having only done a few sample applications. I find myself inheriting a fairly large project where the programmer I replaced used WPF and XAML quite extensively, including lots of the cool features that I avoided in my samples. His code is largely free of code behind classes, while mine used quite a lot of them. (I'm sure I'm not alone in my approach to WPF, which is to treat it like Windows Forms as much as possible. I'm not saying that's good, but I'm sure that a lot of people do it. My predecessor, however, didn't. The result is that his code is rather alien to me. It also doesn't help that he used the DevExpress libraries, and I have no clue how to use those.)
At any rate, I have the following XAML.
<DataTemplate x:Key="LogPullTemplate">
<ListView HorizontalAlignment="Left" VerticalAlignment="Top" ItemsSource="{Binding MyRows}">
<ListView.View>
<GridView>
<GridViewColumn Header="Time" DisplayMemberBinding="{Binding Path=eventTime}"></GridViewColumn>
<GridViewColumn Header="Directory" DisplayMemberBinding="{Binding Path=directory}"></GridViewColumn>
<GridViewColumn Header="Number of files" DisplayMemberBinding="{Binding Path=numLogFile}"></GridViewColumn>
<GridViewColumn Header="Number of Successes" DisplayMemberBinding="{Binding
Path=numPass}"></GridViewColumn>
<GridViewColumn Header="Number of Fails" DisplayMemberBinding="{Binding Path=numFail}"></GridViewColumn>
<GridViewColumn Header="Number Unknown" DisplayMemberBinding="{Binding Path=numUnknown}"></GridViewColumn>
</GridView>
</ListView.View>
</ListView>
</DataTemplate>
There's a control that has a DataTemplateSelector which, when invoked, will return that DataTemplate, and will show a listview on the control. That's good. It has the columns with the headers just like the XAML specifies, but it doesn't have any data.
The object MyRows is a public property of the class that needs the DataTemplate. In it's current incarnation, it's an ObservableCollection, but I've tried a List and also a List of dataRows. Currently, it's declared like this.
publicObservableCollection<TranscriptLogging.LogPullEvent> MyRows { get;set; }
(TranscriptLogging.LogPullEvent is a custom object with properties named eventTime, directory, numLogFile, etc...) There are plenty of perfectly legitimate data items in the list of LogPullEvent objects.
Because it is creating the ListView, I assume that the problem is in the data binding. I've tried a few variations (such as including Path=) in the binding expression, but I still get no data.
Any suggestions?
