Avoid validation in certain conditions

Question

Dear experts

I have one windows application and i am residing forms and user controls on different conditions in MDI parent form
My problem is that if i click some button on MDI parent form it should not execute validation of child control
Means if i validate textbox not to allow blank on leave event and if it is blank then even if i click MDI parent form button when that textbox is blank and control is in textbox it should get clicked without validating textbox

I didn't follow all of that but : 1) If you set the TextBox's CausesValidation property to false then that will cause both its Validating and Validated events to be suppressed. 2) If you're doing the validation in the TextBox's Leave eventhandler then you'll have to create your own bool field to suppress validation and set that to false. The code in the eventhandler should then check that bool field before carrying out validation.
