Free asian mobile sex chat - Tab control validating

Ideally, I think the best solution is not to leave a tab until the validating event has completed successfully. According to MSDN events happen in following order: Focus events occur in the following order: 1.. Thanks Dennis "Alex S" Hi, Dennis did you try to hook Tab Page. loop all the controls on the tabpage, then judge if each control is the default value(We suspect the default value is not the valid value), if it is the default value, does not allow the index change. You may add a custom validating type event for each tabpage, then when registering event handler for child control's Validating event, you should also register it for the tabpage custom event, then in Tab Control.

Tab control validating

The reason to ask the user to save in the validating event is that I try to make user controls that are responsible for their own data. I tried the leave event of the user control, but that gives the same behavior. The Selected Page Changing event is handled to show a message box that asks an end-user whether the changes made must be saved.

Hi, I'm using and doing various validation on controls using the Validating event and setting the e. This works fine on everything apart from when the user hits a tab on a tab control... The events occurs in this order: Leave Validating Validated Lost Focus So unless you are putting in e.

I've made some changes to your code and everything works fine for me.

Is there an event that can be used for the purpose? If the changes must be saved, the user control's Save method is called.

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? Another approach would be to somehow cancel the pending validating event when the user selects another tab page. I can setup a tab page leave event, but to what benefit? According to MSDN events happen in following order: Focus events occur in the following order: 1.. I would allow user to fill pages in the order he/she prefers and jump between them at will. Being able to do that might help for my particular circumstances. For certain control, once it has focus, it will validate its data for closing, leaving, etc.. So the only problem when changing pages is when all the child controls on the form have no focus, then swith pages will not trigger the child controls' validating events.

The problem I am experiencing is when a control fails its validating event and the user clicks another tab things get messy. Thanks Dennis "Alex S" Hi, Dennis did you try to hook Tab Page. Otherwise it is better to use Wizard-style approach, when consecutive screens are shown each after another and errors on screen N do not allow to go to screen N 1. Another approach would be to somehow cancel the pending validating event when the user selects another tab page. I can setup a tab page leave event, but to what benefit? According to MSDN events happen in following order: Focus events occur in the following order: 1.. For this issue, I think there are 2 workarounds: 1.

The Validating event is when a control is about to lose focus.

When I tried to change the tab page, it fired the Validating event, and cancelled, just like it is supposed to.

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.

The problem I am experiencing is when a control fails its validating event and the user clicks another tab things get messy. 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.

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.
