TextBox Does Not Fire Events!

[Onur Tezic]

Hi All,

I have created a class which inherits from RADTextBox and override the OnKeyPress() method.

public class RegExpRadTextBox : RadTextBox
{
string _keyRegExp;
public string KeyRegExp
{
get { return this._keyRegExp; }
set { this._keyRegExp = value; }
}

protected override void OnKeyPress(KeyPressEventArgs e)
{
if (!string.IsNullOrEmpty(this._keyRegExp))
{
if (!Regex.IsMatch(e.KeyChar.ToString(), this._keyRegExp))
{
e.Handled = true;
}
}

base.OnKeyPress(e);
}
}

But when i type some text, nothing happens (Keypress Event Firing/Raised).

(Keydown is also doesnt work.) 

What should i do? 

Thanks.

Hi Onur Tezic,

Thank you for your question. This happens because we are using a Microsoft TextBox inside RadTextBox. When you press a key, the microsoft text box is focused and it gets the key down / pressed notification, not RadTextBox. You should be able to implement your functionality with the help of TextChanging and TextChanged events that RadTextBox provides.

Kind regards,
