RadTabStrip with RadMultipage (user controls) save current page on tab click

[ADT]

Hello all and Thanks for any help in advance. I am using a main web page that holds a RadTabStrip with RadMultipage. Each page for the Multipage is a seperate user control. I am using RenderSelectedPageOnly for this. Currently I have the tabs working and loading the proper pages. An issue I am running into is that when a user is on the first tab and clicks on the second tab, I want to force a save of the first tab. Anyone have input on how I can accomplish this. I notice on the tab click for the second tab it does the validation but if the required fields are entered it goes to the next tab without saving.

Here is my main .aspx page

Any input is greatly appreciated. I was looking through the Demo's online but didn't find anything very thorough with Multipage and user controls.

Thanks again,

Hello Austin,

I am not quite sure, that I had understood the issue you are facing. If the RequiredFieldValidatiors does not validate the page (e.g. there are more fields to fill), the page will not postback, when a Tab is clicked. If the Page is valid, you could use the OnTabClick, in order to save the current data. Would you elaborate a bit more on the faced issue?

I can get the page to postback and go to whatever tab the user selects, my issue was where do I force the save?

As displayed in my code below, I have a btnSave event that occurs, when the user clicks another one of the tabs I want the save to occur. But where do I catch that TabClick event? In the User control or on the main .aspx page that hosts the RadTabStrip/RadMultiPage? And if I have to do it on the main .aspx page, how do I fire off the code in a user control?

I'm new to TabStrips/Multi-page with user controls. I've done work on other pages before where all the code for the TabStrip/Multipage was all on 1 .aspx page, but that is not the most effective way as all the code is all in one page and become a jumbled mess.

That clear it up a bit?

Thanks,

Austin

Hello Austin,

You should handle the OnClick event in the main Page and access the controls in the UserControl, in order to extract the filled values. I would suggest you to refer to our online Wizard demo, demonstrating a similar functionality. Instead of a Save button, in the demo is used a Next button and the data from the UserControls is extracted and saved in the Preview user control. The button is located in the user controls, but you could use the approach, in order to access the controls in the UserControls.
