I have a WPF DataGrid
that contains some data. I would like to set the width of the columns such that the content fits in and never gets cropped (instead, a horizontal scroll bar should become visible). Additionally, I want the DataGrid
to fill the whole place available (I am working with a DockPanel
). I am using the following code (simplified):
<DataGrid ItemsSource="{Binding Table}">
<DataGrid.Columns>
<DataGridTextColumn MinWidth="100" Width="Auto" Header="Column 1" Binding="{Binding Property1}" />
<DataGridTextColumn MinWidth="200" Width="Auto" Header="Column 2" Binding="{Binding Property2}" />
</DataGrid.Columns>
</DataGrid>
This apparently does not work out of the box with Width="Auto"
as it always looks something like this:
This obviously looks ugly. I would like to have the whole row selected, or, which would be much better, the columns to fill the whole width, but as one can see, this does not work.
If I use Width="*"
instead, the content of the columns gets cropped which is even worse for me.
I found a similar question here, and a workaround was posted there. This may work, but I am working with the MVVM pattern, so the ItemsSource gets updated in the ViewModel and I cannot think about a way of doing it from there, because I cannot access the ActualWidth
property of the DataGridColumn
. Also, I would like to do it only in XAML if possible.
I would appreciate any help. Thanks!
Edit: As I still don't have a clue what to do about it, I start a small bounty. I would be very happy about a suggestion what one could do about my problem. Thanks again!
Edit 2: After saus' answer I thought about the options again. The problem is that I need to update the Width
and the MinWidth
properties also during the application is running, so not only after loading the window. I already tried to do something like
column.Width = new DataGridLength(1, DataGridLengthUnitType.Auto);
column.MinWidth = column.ActualWidth;
column.Width = new DataGridLength(1, DataGridLengthUnitType.Star);
in some event that is fired when the underlying ItemsSource
of the DataGrid
is updating. However, this does not work, as the ActualWidth
property does not seem to change after setting the Width
on Auto
. Is there an option to somehow "repaint" it in order to get the ActualWidth
property updated? Thanks!
