Pasting Value With Spaces in Front and Back Does Not Work

Environment

Product Version	2020.3.1020
Product	RadNumericUpDown for WPF

Description

Pasting a copied numeric value that contains untrimmed text does not work. In this case nothing happens.

Solution

Subscribe the RadNumericUpDown control to the DataObject's Pastring event and implement the pasting manually.

DataObject.AddPastingHandler(this.numericUpDown, OnNumericUpDownPaste); 

private void OnNumericUpDownPaste(object sender, DataObjectPastingEventArgs e) 
{ 
    var copiedString = e.DataObject.GetData(typeof(string)) as string; 
    if (copiedString != null) 
    { 
        copiedString = copiedString.Trim(); 
        double number = 0; 
        var success = double.TryParse(copiedString, out number); 
        if (success) 
        { 
            this.numericUpDown.SetCurrentValue(RadNumericUpDown.ValueProperty, number); 
            e.CancelCommand(); 
        } 
    } 
}
