How the bind the string value to the RadSilder?

[Justin]

Is it possible to get the string data from the database and bind to the RadSlider control?

Thanks

Hi Justin,

If you get a string from the database, you can use converters from string to double like so:

<telerik:RadSlider
            Value="{Binding Value, Mode=TwoWay, Converter={StaticResource ByteToDoubleConverter}}"

public class ByteToDoubleConverter : IValueConverter
   {
       public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
       {
           double? result = 0.0;
           if (value is string)
           {
               double nonNullableResult;
               Double.TryParse(value as string, out nonNullableResult);
               return nonNullableResult;
           }
           else
               if (value is double?)
           {
               result = value as double?;
           }
           else if (value is int?)
           {
               result = (double)(value as int?);
           }
           else if (value is byte?)
           {
               result = (double)(value as byte?);
           }
           return result;
       }
       public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
       {
           throw new NotImplementedException();
       }
   }

Feel free to ask if you need further help.

Hi,

Thanks for your replying.

What I am trying to do is  to dispay some string value on the Slider based on the data in the database.

I can use converter to implement the convertion between string and double.

But the problem is the string value is based on the value in database.

Hope that makes sense.

Thanks

Hello Justin,

In this case inspect what is the value from the database and update the Convert method accordingly.
