So I have an XML file which I read in then display the data onto a DataGrid. Once I bind the DataView of the XML file to the ItemsSource of the datagrid I then attempt to hide the 4th column that will be created (it's an ID which I don't want to show) but receive an error
System.Windows.Markup.XamlParseException
HResult=0x80131501
Message='The invocation of the constructor on type 'MoneyLog.MainWindow' that matches the specified binding constraints threw an exception.' Line number '6' and line position '9'.

StackTrace:
at System.Windows.Markup.WpfXamlLoader.Load(XamlReader xamlReader, IXamlObjectWriterFactory writerFactory, Boolean skipJournaledProperties, Object rootObject, XamlObjectWriterSettings settings, Uri baseUri)
Inner Exception 1:
ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
The Code I use:
DataGrid.Columns[4].Visibility = Visibility.Collapsed;
From the error I can see that apparently my number (4) was out of range therefore I assume the table must not of been create yet. To fix this i wrote a crude hack that delays the chunk of code by half a second and this fixes the problem...?
DataGrid.ItemsSource = dataView;
var timer = new DispatcherTimer { Interval = TimeSpan.FromMilliseconds(500) };
timer.Start();
timer.Tick += (sender, args) =>
{
timer.Stop();
DataGrid.Columns[3].Width = 250;
DataGrid.Columns[4].Visibility = Visibility.Collapsed;
DataGrid.CanUserAddRows = false;
DataGrid.IsReadOnly = true;
};
My question is there another way to do this without this whole timer workaround?
