wpftoolkit DataGridTemplateColumn Template binding
- by Guillaume
I want my datagrid columns to share a cell/celledit template.
I have the solution do that (thanks to WPF DataGridTemplateColumn shared template?). Now what I would love to is improving the readability by avoiding all the node nesting.
My current view looks like that:
<wpftk:DataGrid ItemsSource="{Binding Tests}" AutoGenerateColumns="False">
<wpftk:DataGrid.Resources>
<DataTemplate x:Key="CustomCellTemplate">
<TextBlock Text="{TemplateBinding Content}"/>
</DataTemplate>
<DataTemplate x:Key="CustomCellEditingTemplate">
<TextBox Text="{TemplateBinding Content}"></TextBox>
</DataTemplate>
</wpftk:DataGrid.Resources>
<wpftk:DataGrid.Columns>
<wpftk:DataGridTemplateColumn Header="Start Date">
<wpftk:DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<ContentPresenter ContentTemplate="{StaticResource CustomCellTemplate}" Content="{Binding StartDate}"/>
</DataTemplate>
</wpftk:DataGridTemplateColumn.CellTemplate>
<wpftk:DataGridTemplateColumn.CellEditingTemplate>
<DataTemplate>
<ContentPresenter ContentTemplate="{StaticResource CustomCellEditingTemplate}" Content="{Binding StartDate}"/>
</DataTemplate>
</wpftk:DataGridTemplateColumn.CellEditingTemplate>
</wpftk:DataGridTemplateColumn>
<!--and again the whole block above for each columns...-->
</wpftk:DataGrid.Columns>
</wpftk:DataGrid>
What I would like to achieve is to bind the value at the DataGridTemplateColumn level and propagate it to the template level. Anyone know how to do that?
What I tried to do is something like that:
<wpftk:DataGrid ItemsSource="{Binding Tests}" AutoGenerateColumns="False">
<wpftk:DataGrid.Resources>
<DataTemplate x:Key="CustomCellTemplate">
<TextBlock Text="{Binding}"/>
</DataTemplate>
<DataTemplate x:Key="CustomCellEditingTemplate">
<TextBox Text="{Binding}"></TextBox>
</DataTemplate>
</wpftk:DataGrid.Resources>
<wpftk:DataGrid.Columns>
<wpftk:DataGridTemplateColumn Header="Start Date" Binding="{Binding StartDate}" CellTemplate="{StaticResource CustomCellTemplate}" CellEditingTemplate="{StaticResource CustomCellEditingTemplate}"/>
<wpftk:DataGridTemplateColumn Header="End Date" Binding="{Binding EndDate}" CellTemplate="{StaticResource CustomCellTemplate}" CellEditingTemplate="{StaticResource CustomCellEditingTemplate}"/>
</wpftk:DataGrid.Columns>
</wpftk:DataGrid>
Obviously the binding porperty is not a valid property of the DataGridTemplateColumn but maybe by playing with the datacontext and some relative source could do the trick but frankly I can't find a way to implement that.
Not sure if what I want is possible and i'm willing to accept a "no way you can do that" as an answer
NOTE: The TextBlock/TextBox in the template is just for test (the real template is much more complex) DataGridTextColumn will not do the trick
Thanks in advance
