>I have an ASP.NET page where entry in one of the text boxes have to be validated against a database. I put the validation code in the OnTextChanged method on the textbox. It works except if a user enters anything in the textbox and then immediately clicks on the Submit button. Then, the OnTextChanged method does not fire and entry is not validated.

Use an Input Validation Control

For VB.NET

Sub cmdSubmit_Click(s As Object, e As EventArgs)
	If Page.IsValid Then
		Message.Text “Looks good!”
                ‘ Put your code here
	End If
End Sub

C#

Private void cmdSubmit_Click(object s, Systems.EventArgs e)
{
	if (Page.IsValid)
	{
		Message.Text “Looks good!”
		// Put your code here	
        }
}
