What do you want to validate? Stirng, int, double, bool?

}

String,int and Decimal

[Mitja Bonca]

You can test is in this way:
put on the from:
- textBox
- button
- label

Now create a method for a button_Click event and put use this code on it:

private void button1_Click(object sender, EventArgs e)
        {
            string sValue = textBox1.Text;
            int intValue = 0;
            decimal decValue = 0M;
            
            bool bValidating = int.TryParse(sValue, out intValue);
            if (!bValidating)
            {
                bValidating = decimal.TryParse(sValue, out decValue);
                if (!bValidating)
                    label1.Text = sValue + " is a string";
                else
                    label1.Text = sValue + " is a decimal";
            }
            else
                label1.Text = sValue + " is a integer";
        }

Hope it helps,

Can i Use it with the Validating Event

[Mitja Bonca]

Sure you can, but the Validating even it self will do nothing. You have to put the code inside of it, ok ?
