Is it possible to format a string using StringFormat...
for example.. my model:
public class MyModel
{
public string Code { get; set; }
}
Possible values for Code are: '00000101001', '00000201001', etc...
When binding, i´d like to show: For '00000101001' -> '000001-01' (Ignore last 3 characters) For '00000201001' -> '000002-01' (Ignore last 3 characters)
If its possible using stringformat to achieve this, would be nice instead have to implement by my own.
Your question asked about BINDING a string in WPF (without altering the internal content of the string), and among the preferred strategies for solving this is to use a converter, here's an example that does what you're looking for (display the first 10 characters only)...
public class CodeConverter : MarkupExtension, IValueConverter
{
public object Convert(object value, Type targetType, object parameter,
System.Globalization.CultureInfo culture)
{
try
{
string result = value.ToString();
if (result.Length > 10)
{
// code in your exact requirements here...
return result.Substring(0, 10);
}
return result;
}
catch{}
return value;
}
public object ConvertBack(object value, Type targetType, object parameter,
System.Globalization.CultureInfo culture)
{
return null;
}
public override object ProvideValue(IServiceProvider serviceProvider)
{
return this;
}
}
In your Xaml, simply specify this class in your binding...
{Binding Code, Converter={StaticResource CodeConverter}
And you're good to go!
Just use a conversion function. E.g:
public static string Convert(string raw)
{
return raw.Substring(0,6)+"-"+raw.Substring(6,2);
}
Console.WriteLine (Convert("00000201001"));
//output= 000002-01
Could do something like this:
return (Int64.Parse("00000101001") / 1000).ToString("000000-00");
Regards.
