TimeSpanStringConvertEventArgs Class

Namespace: DevExpress.XtraScheduler.Native

Assembly: DevExpress.XtraScheduler.v24.1.Core.Desktop.dll

NuGet Package: DevExpress.Scheduler.CoreDesktop

Declaration

public class TimeSpanStringConvertEventArgs :
    EventArgs

Remarks

The TimeSpanStringConvertEventArgs class introduces properties required to implement conversion using the HumanReadableTimeSpanHelper.ConvertToString and HumanReadableTimeSpanHelper.ParseString events. Note, that TimeSpanStringConvertEventArgs objects are automatically created, initialized and passed to the corresponding event handlers.

Example

This example demonstrates how to use the HumanReadableTimeSpanHelper instance to implement the custom conversion of a TimeSpan value to a string and vice versa. To do this handle the HumanReadableTimeSpanHelper.ParseString and HumanReadableTimeSpanHelper.ConvertToString events and use the members of the corresponding TimeSpanStringConvertEventArgs object.

using DevExpress.XtraScheduler.Native;
// ...

// Handle the ParseString and ConvertToString events of the HumanReadableTimeSpanHelper.
HumanReadableTimeSpanHelper.ParseString += new TimeSpanStringConvertEventHandler(OnParse);
HumanReadableTimeSpanHelper.ConvertToString += new TimeSpanStringConvertEventHandler(OnToString);

// Custom parsing of a string to a TimeSpan value.
void OnParse(object sender, TimeSpanStringConvertEventArgs e) {
   double val;
   try {
         string number = e.StringValue.Substring(0, e.StringValue.IndexOf(" milliseconds"));
         val = Convert.ToDouble(number);
   }
   catch {
         val = 0;
   }

   e.TimeSpanValue = TimeSpan.FromMilliseconds(val);
   e.Handled = true;
}

// Custom conversion of a TimeSpan value to a string.
void OnToString(object sender, TimeSpanStringConvertEventArgs e) {
   e.StringValue = e.TimeSpanValue.TotalMilliseconds.ToString() + " milliseconds";
   e.Handled = true;
}
