The server side validation routine must be called from the control's Server Validate event handler. The basic syntax for the control is as given: The Validation Summary control does not perform any validation but shows a summary of all errors in the page.
The server side validation routine should be written in any . The summary displays the values of the Error Message property of all validation controls that failed validation.
Drumm" Is there a way to prevent the user from leaving a tab on a Tab Control until all the controls on that tab have finished validating? Ideally, I think the Dennis, I expect that while you are executing code in Leave event your other page cannot receive focus (even if can, there will be no interaction possible if you don't call App. Hence, if your validation in Leave fails you can always go back to original page and select / focus corresponding control. The problem I am experiencing is when a control fails its validating event and the user clicks another tab things get messy.

The validation control classes are inherited from the Base Validator class hence they inherit its properties and methods.
Therefore, it would help to take a look at the properties and the methods of this base class, which are common for all the validation controls: The Regular Expression Validator allows validating the input text by matching against a pattern of a regular expression.
Note: Fixes previously available in Cognos BI 10.2.1 FP1 Feature Bundle are included in Cognos BI 10.2.1 FP3.
Ideally, I think the best solution is not to leave a tab until the validating event has completed successfully. Being able to do that might help for my particular circumstances. If you have multi-tab entry form final validation should occur only when final tab page is filled and confirmed. I guess maybe I should have asked only how to prevent a user from leaving a tab page. I think you should hook the Validating event for all the controls on your form.

I guess maybe I should have asked only how to prevent a user from leaving a tab page. You can combine this with Validating event, where you can set Cancel=true to prevent further events after Validating. Generally speaking, I would suggest to reconsider whole validation scheme you use now - whatever unusual things you are trying to do. Ideally, I think the Hi Dennis, Based on my understanding, you want to validating all the controls on the tabpage before switch pages.
Now you will see the browser posting back to the server, but the result will be the same - the validator still works!
Right now, the button does nothing, besides posting back if the page is valid.
