A table which has binding ability and also manual editing - c#

What I want is to have a table having a first column with every row named by me one by one, not binding to some property. But all of the second column should be binded to a property. I cannot do these two with gridview since it only makes binding and does not let me to write something manually. On the other hand, I havent seen any flowdocument table tutorial in which someone mention binding. So what is the proper object suitable to fulfill mentioned two things?

ListView and GridView should meet your requirements. You have the ability to set bindings on the GridViewColumns by using DisplayMemberPath or in the CellTemplate. You can also choose not to use bindings in a column.
Take this for example:
<ListView ItemsSource="{Binding NameValuePairs}">
<ListView.Resources>
<DataTemplate x:Key="FirstCellTemplate">
<Grid Width="100">
<TextBox Width="75"/>
</Grid>
</DataTemplate>
</ListView.Resources>
<ListView.View>
<GridView>
<GridViewColumn CellTemplate="{StaticResource FirstCellTemplate}"/>
<GridViewColumn DisplayMemberBinding="{Binding Name}"/>
<GridViewColumn DisplayMemberBinding="{Binding Value}"/>
</GridView>
</ListView.View>
</ListView>
NameValuePairs is an ObservableCollection<NameValuePair> and NameValuePair is a view model with a Name and Value properties. The first column is contains a TextBox on each row, the second is a TextBlock with the Name, and the third is a TextBlock with the Value.

How to Bind Values from List in BarChart

I have an application which is check the incoming Mails on the Server and refresh a List with X-Values in it. Now I want to Plot the incoming Mail count in a Live Chart. I use http://lvcharts.net for this.
I have two classes a Mail Object with the Count and a TimeStamp in it and a List Class with all Mail Objects in it.
Here is my sample(pseudo) XAMl code:
<liveCharts:BarChart Name="MailChart" Grid.Row="1" Grid.Column="0">
<liveCharts:BarChart.Series>
<liveCharts:BarSeries Title="Mails" Values= "{Binding MailCountList.Count}"></liveCharts:BarSeries>
......
......
<liveCharts:BarChart.AxisY>
<liveCharts:Axis Title="Time" Labels="{Binding MailCountList.Timestamp}">
......
The Objects are in a normal List with automatically Refesh I use MVVM.
My Question is:
How can I bind a List to a XAML Value Series ?
I have used an ObservableCollection to view the Content and a normal list to fill sort etc. the Xaml Code Looks Like:
<ListView ItemsSource="{Binding TableList}" Grid.Row="0">
<ListView.View>
<GridView>
<GridViewColumn Width="50" Header="ID" DisplayMemberBinding="{Binding ID}"/>
<GridViewColumn Width="180" Header="Name" DisplayMemberBinding="{Binding Name}"/>
<GridViewColumn Width="100" Header="Group" DisplayMemberBinding="{Binding Group}"/>
<GridViewColumn Width="85" Header="Version" DisplayMemberBinding="{Binding Version}"/>
</GridView>
</ListView.View>
</ListView>
The Source of the ListView is in the ItemSource and to Display Multiple Rows I use GridViewColumn with Binding to the Object Values from the List in "DisplayMemberBinding"

How do you use a CellTemplateSelector with databindings on a GridView?

I'm trying to bind to properties on my GridView's DataContext and use a DataTemplateSelector to assign the correct template to the cell, but I can't seem to find the correct way to do this. Binding to DisplayMemberBinding overrides the template selector, but setting the CellTemplateSelector property binds to the DataContext rather than the properties I want to select templates for.
This answer seems to describe exactly what I'm looking for, but I'm having trouble finding information on how to implement what it describes: https://stackoverflow.com/a/12519433/1756960 .
This is what I tried using that isn't working (simplified for posting):
<ListView ItemsSource="{Binding Items}">
<ListView.View>
<GridView>
<GridViewColumn Header="Name"
DisplayMemberBinding="{Binding Name}"
CellTemplateSelector="{StaticResource ContentTypeTemplateSelector}" />
<GridViewColumn Header="Data"
DisplayMemberBinding="{Binding}"
CellTemplateSelector="{StaticResource ContentTypeTemplateSelector}" />
</GridView>
</ListView.View>
</ListView>
The first thing I would recommend doing is to differentiate your Content Template selectors in one of two ways. The First is to simply have more than one template selector class. the second is to have two instances, whose templates are assign different bindings.
<Resources>
<ns:TemplateSelector x:Key="NameTemplateSelector">
<ns:TemplateSelector.Template1>
<DataTemplate>
<!-- Something bound to Name -->
</DataTemplate>
</ns:TemplateSelector.Template1>
</ns:TemplateSelector>
<ns:TemplateSelector x:Key="DataTemplateSelector">
<ns:TemplateSelector.Template1>
<DataTemplate>
<!-- Something bound to Data -->
</DataTemplate>
</ns:TemplateSelector.Template1>
</ns:TemplateSelector>
The reference to Attached Properties (see MSDN) would have you make a property, attach it to the template selector, and then access that data from the TemplateSelector's code.

Control suggestions that function like a multi column listBox

I've looked at a bunch of different controls(ListView, GridView, etc.) and can't decide which makes the most sense for me to use.
I want something that looks and functions just like a listBox with the ability to select a row with a single click, except it would contain data with multiple columns.
I'm just looking for suggestions on which control to use and how I would go about having it select a row(whether it's a selectionMode or an onClick function or what). Since I'm new to these controls I'd like some direction on which tag to place those selection options, I think I can figure out the rest however.
Thanks :)
I like using the ListView that contains a GridView as it's view. Here's how I defined it in XAML:
<ListView Name="lstCurrentInvoices" Grid.Row="4" Margin="0,0,0,0" SelectionMode="Extended" ToolTip="Invoices included in invoice file." IsTabStop="True" TabIndex="8">
<ListView.View>
<GridView>
<GridViewColumn Width="40" Header="ID" DisplayMemberBinding="{Binding ClientId}"/>
<GridViewColumn Width="170" Header="Name" DisplayMemberBinding="{Binding ClientName}"/>
<GridViewColumn Width="80" Header="Date" DisplayMemberBinding="{Binding InvoiceDate}"/>
<GridViewColumn Width="40" Header="Frequency" DisplayMemberBinding="{Binding Frequency}" />
</GridView>
</ListView.View>
</ListView>
This way you kind of get the best of both worlds. In this example, you can have multiple rows selected. You can detect which rows have been selected and grab the objects from you data source. It's really quite powerful. Hope this helps

Generic DataTemplate used in multiple GridViewColumns

I have a GridView that displays some values:
<ListView ItemsSource="{Binding MyDataSource}">
<ListView.View>
<GridView>
<GridViewColumn Header="Date1" DisplayMemberBinding="{Binding Date1}" />
<GridViewColumn Header="Date2" DisplayMemberBinding="{Binding Date2}" />
...other Columns, not necessarily containing dates...
</GridView>
</ListView.View>
</ListView>
This works fine. Now I want to create a data template that formats a date in a specific way:
<DataTemplate x:Key="MySpecialDate">
<TextBlock Text="{Binding StringFormat={}{0:yyyy.MM.dd}}" />
</DataTemplate>
Adding CellTemplate won't work as long as DisplayMemberBinding is specified. Thus, I have to remove the DisplayMemberBinding attribute:
<GridViewColumn Header="Date1" CellTemplate="{StaticResource MySpecialDate}" />
<GridViewColumn Header="Date2" CellTemplate="{StaticResource MySpecialDate}" />
Here's the question: Now that DisplayMemberBinding is gone, how do I tell the GridView which property to display? GridViewColumn does not have a DataContext property.
Of course, I could put the name of the property (Date1 resp. Date2) into the DataTemplate, but then I would need one template for each property and that would defeat the whole purpose of having a template.
<!-- I don't want that -->
<DataTemplate x:Key="MySpecialDate1">
<TextBlock Text="{Binding Date1, StringFormat={}{0:yyyy.MM.dd}}" />
</DataTemplate>
<DataTemplate x:Key="MySpecialDate2">
<TextBlock Text="{Binding Date2, StringFormat={}{0:yyyy.MM.dd}}" />
</DataTemplate>
Related to your question is mine: Pass multiple resources into a DataTemplate which I finally found a solution for.
I think you cannot get around the definition of a template for every such date. But depending on the complexity of your display template this solution keeps the additional DataTemplates code to a minimum:
<DataTemplate x:Key="DateX">
<ContentPresenter ContentTemplate="{StaticResource MySpecialDate}" local:YourClass.AttachedDate="DateX"/>
</DataTemplate>
These additional DataTemplates use an attached property which can then be used by a converter in the DataTemplate "MySpecialDate".
The attached property has to be defined in the code behind. The answer to my own question contains a complete example.
If the format is really that widely used, then you could use the following
In DateTimeColumn.cs
public class DateTimeColumn : GridViewColumn
{
protected override void OnPropertyChanged(PropertyChangedEventArgs e)
{
base.OnPropertyChanged(e);
if (Equals(e.PropertyName, "DisplayMemberBinding") && DisplayMemberBinding != null)
{
DisplayMemberBinding.StringFormat = "{0:yyyy.MM.dd}";
}
}
}
XAML code...
<local:DateTimeColumn DisplayMemberBinding="{Binding Date1}" />
(I don't like the format as a magic string, but the code can be modified as needed.)

WPF - ItemsSource equivalent for Table in FlowDocument?

I'm trying to create a Table inside a FlowDocument inside a FlowDocumentPageViewer, as seen in this tutorial. I've never created a table in WPF before, and I was expecting there to be an ItemsSourceproperty to which I could bind, like with a ListBox. I want to customize the template for each row, and I want each row's source to be an item in a collection that I pass to the entire table. So I'll have a List<MyClass> instance that would be passed to the table, and each row would show a single MyClass. How can I do that? Do I not want to use a Table within a FlowDocument? The reason I wanted to use some kind of tabular format is so that I can have a single row of column names that applies to all the rows.
I think what I wanted was to use ListView, thanks to this tutorial:
<ListView Grid.Row="0" ItemsSource="{Binding Path=MyList}" MinWidth="400"
MinHeight="200">
<ListView.View>
<GridView>
<GridView.Columns>
<GridViewColumn
DisplayMemberBinding="{Binding Path=MyFirstField}"
Header="First Field"/>
<GridViewColumn
DisplayMemberBinding="{Binding Path=MySecondField}"
Header="Second Field"/>
</GridView.Columns>
</GridView>
</ListView.View>
</ListView>
