DataGridCell Style Problem

Kevin Marois

I'm creating a WPF DataGrid. The data source is a DataTable created in the VM. [See this pic](https://1drv.ms/u/s!AjBmoYAYz\_v2hBJl1Yj0BBLCyDbW?e=gcMT3H). I'm creating a DataTable in the VM, then binding the DataGrid to it. That part all works fine. I now want to apply a cell style: View Model

string[] columnNames = (from dc in BudgetTable.Columns.Cast()
select dc.ColumnName).ToArray();

// Go through each column
foreach (string item in columnNames)
{
//Creating binding
Binding binding = new Binding(item);
string styleName = "";

if (item == "Type")
{
	binding.Mode = BindingMode.OneTime;
	styleName = "budgetGridCellStyle";
}
else
{
	binding.Mode = BindingMode.TwoWay;
	binding.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
	styleName = "dataGridCurrencyCellStyle";
}

var style = Application.Current.FindResource(styleName) as Style;
			
// Bind the column
var col = new DataGridTextColumn()
{
	Header = item,
	Binding = binding,
	Visibility = Visibility.Visible,
	CellStyle = style
};

DataGridColumns.Add(col);

}

Style

<Setter Property="TextBlock.Text" Value="{Binding StringFormat={}{0:0.##}}"/>
<Setter Property="IsEnabled" Value="{Binding AreFieldsEnabled}"/>

</Style>

The setters won't work: 1. The string format setting is not being applied no matter what I change it to. What's the right way to do this? 2. The IsEnabled causes a BindingExpression error. AreFieldsEnabled is a bool property on the VM. How do I reference that from this style? Thanks

If it's not broken, fix it until it is. Everything makes sense in someone's mind. Ya can't fix stupid.
