Overall validation description
In the View we set ValidatesOnExceptions=True.
<TextBox Name ="IntValueTextBox" Text="{Binding IntValue, Mode=TwoWay, ValidatesOnExceptions=True}">
In ViewModel the property that we want bind to and want to validate looks as follows:
[System.Diagnostics.DebuggerHidden()]
public string IntValue
{
get { return intValue.ToString(); }
[System.Diagnostics.DebuggerHidden()]
set
{
int temp;
if (!Int32.TryParse(value, out temp))
{
throw new Exception("Please enter a valid integer value");
}
else
{
intValue = Int32.Parse(value);
}
}
}
private int intValue;
Hiding validation exception for Visual Studio Debugger
While using validation (get;set; property approach) validation expceptions are thrown as follows:
throw new Exception("Please enter a valid integer value");
It causes quite disturbing effect of receiving errors in Visual Studio debugger. When using:
[System.Diagnostics.DebuggerHidden()]
in every property that we validate and its get; set; methods we will hide these error from the debugger.
