advanced validation ....urgent .net

Hi I am writing a large program where I am using three text boxes. I am performing validation controls on these text boxes however there are some conditions Names of textboxes 1. x 2. y 3. z The conditions are 1. x , y , z should be numeric. 2. x and y can be blank ( x = “” , y = “”) at a time 3. z can never be blank, it should always have a numeric value. 4. if x has a value y cannot be blank and x should be non negative 5. if y has a value x cannot be blank and y should not be non negative. 6. if x and y have values y > x 7. z should be non negative A message box should pop up each time the user clicks a button with the appropriate error ( eg : x cannot be negative , or y cannot be greater than x , etc… ) Since I am actually dealing with cells in a data grid I cannot use any sort of validation controls. I need to perform the validation using code. I am using visual studio 2005 , Visual Basic Any sort of help will be gratefully appreciated.

I don't have time to give you a complete answer since it's my bedtime. Nevertheless, I have used validation controls with datagrids in .NET 1.1. I believe I created child validation controls that occupied the same cell as the active input control (e.g. textbox). I had some elaborate condition like you do. I believe I had to write some javascript to call some of Microsoft's validation javacript code to perform these special conditions. I don't know if this could be done with .NET 2.0, or there may be a more standard way of doing it.

Welcome to the Code Project. Please don't post the same question all over the place.
