Runtime validation Webcontrol

[brandonjack007]

I have a webcontrol that extends from
System.Web.UI.WebControls.WebControl. It has 3 properties
SelectedDate, MaximumDate,MinimumDate. During design time I use
ArgumentException to ensure
MinimumDate<SelectedDate<MaximumDate. How can I achieve this
validation during runtime.

You can add a range validator to the user control. set it's minimum
value and maximumvalue and the control to validate and you're all set.

I was too fast in answering I see now. You're inheriting from
WebControl, not WebUserControl.

In that case you need to implement the IValidator interface and provide
the correct validation details in there.

I implement IValidator interface in the control
Is this the correct way cos it fails....
public bool IsValid
{
get {return mIsValid;}
set { mIsValid = value;}
}

public string ErrorMessage
{
get { return mErrorMessage; }
set { mErrorMessage = value; }
}

public virtual void Validate()
{
this.IsValid = true;
if(!IsDate(this.selectedDate.ToString()))
{
this.IsValid = false;
}
if (this.selectedDate<this.MinimumDate ||
this.selectedDate>this.MaximumDate)
{
this.IsValid = false;
}
}
