I have a C#.NET MVC3 web app. I have a View that has a List of Models. This list can be long, requiring the user to scroll down on the View. When selecting one of the models in the View to Edit, the user is taken to the Edit View. After submitting the Edit View, the user is redirected back to the List View. However, the List View is now displaying back at the top of the list. How can I redirect the user back to the same position in the List View where they clicked the Edit button?
You would probably be better suited using a modal popup dialog to edit the data, rather than navigating to another page.
While it's possible to do what you want, it's a pain. You would have to get the scroll location via javascript, save it to a hidden field, post that to your edit page, along with record number and anything else, then re-post it back to your original page when you return, then read the post value and scroll to it via javascript.
All that is avoided if you just use a modal edit dialog, then when the dialog goes away the page is still in the same place.

I have used Fresh MVMM. I need to pass a data from one page model to another page model without using init and reverse init.
Eg: I have one toggle button in first content page.
I need to toggled the button based on the selection in second popup page without popup the second PopPopupPageModel.
ReverseInit is worked when popup the second PopPopupPageModel and can easily pass data.
But I need to toogled the button in first page without popup the second page.
Please help...
I have a currently loaded form with different fields in it. Example I am on URL: https://localhost:44300/ where the form is currently displayed. However, once of the fields has a link beside it "View Full List" where in once I click on that it will redirect me to a different view and user can select one value from there.
View full list when clicked will be redirected to: https://localhost:44300/project/organisationfulllist/
Now, once I have selected from the displayed list in that view (radiobutton list), I will click on a [SAVE] button and it should redirect me back to my original form with URL https://localhost:44300/
My question is when I am redirecting to the original view, the previous inputs on several fields were reset. What I want is to preserve these inputs from user. Is there a way to sort of save the session of the previous form?
Save the information in the session once the user clicks "View Full List"
Session["formdata"] = formdata;
Then get it back when you open the form again
FormModel formModel = Session["formdata"] as FormModel;
Is it possible to not redirect when user clicks "View Full List" and keep the selection on the same page? On a pop-up or something.
I want to maintain the Scroll Position between two pages. I have a Page A which has many reports, when user clicks a report, user will be redirected to Page B where the report will be opened to make the changes. After submitting changes, user will be redirected to Page A. Here the problem is, showing the top of the page but I want to show the page at the previous position.
I have tried using this.MaintainScrollPositionOnPostBack = true; but this is working only on the same page but not between the different pages.
I really need to fix this, please give me your thoughts...
The simplest thing to do is probably give every link/report on page A an anchor.
So, for each report you would hide an id attribute somewhere - say the title, so it would be something like <h3 id="report42">Report 42</h3>. Then when you go back from page B, instead of going to www.example.com/pageA.html, you go to www.example.com/pageA.html#report42. This will open the page with the scrollbar at wherever the report42 id is found.
I'm using Joomla to develop a user profile management component with AJAX.
The goal is to allow the user to edit his own user information. There is a lot of information so instead of having one massive form, I decided to make "subforms" or sections. And for the whole thing to be user-friendly I want to send the forms and refresh the user information with AJAX.
Here's an example :
There are two sections, "Basic user info" which displays the first name, the last name and the age of the person and "Extended user info" which displays the occupation, the company and the skills of the person. Each section has an "edit" link (or button) which turns the content into a form (AJAX) allowing the user to modify the presented information. You can only edit one section's information at a time. When the user has finished modifying the data, he sends the form with a "send" link (or button) and the section gets back to simply displaying the information of the section (with the updates that were just made).
So I need to know what is the most efficient way to develop such a component. I thought of two approaches :
1) In the "tmpl" directory of the main component view we the following files :
default_basic.php (displays the basic user information),
default_basic_edit.php (displays the form which allows the user to edit the basic information)
default_extended.php (displays the extended user information),
default_extended_edit.php (displays the form which allows the user to edit the extended info)
default.php (loads each of the display subtemplates with calls to JView::loadTemplate($subtemplate))
When the user clicks on an edit link, an AJAX call is made to the following URI index.php?option=com_userinfo&view=userinfo&subview=basic_edit&format=ajax, which causes the view class to call $this->loadTemplate('basic_edit') after assigning the user information to it.
If the user clicks cancel the same process is used to load the 'basic' template again. And if the user modifies the information and clicks the send link, the form is sent and then the 'basic' template is loaded too.
2) There is only a "default.php" file in the "tmpl" directory which holds the edit version and the display version of each section. But all the edit versions are hidden at first. And when the user clicks on the edit link the display version of the section becomes hidden and the edit version is displayed (using display:none and display:block). Then, if the user clicks the cancel button we do the opposite. And if the user clicks the send button we send an AJAX request to update the data in the database and return the updated user info which will be loaded into the display version of the section. And we finally replace the edit version of the section with its display version.
I know there's a lot of text but in the end it goes down to choosing between refreshing full HTML blocks with AJAX, or just sending the updated info and modifying the content of hidden blocks and then make them appear. So what do you think is the most logical approach, knowing that we are in a Joomla 1.5 environment ? How would you procede ? (maybe there are other ways to create such a component ?)
(I tried both ways and I couldn't entirely make it work so I decided to ask to see if it is a matter of conception...)
Thank you for taking the time to read all the text.
My answer is: why even refresh parts when it can be done without it?
For example when we are talking about basic form elements like text fields and check/radio buttons I would prefer the following: on a successful save/send simply display a nice message like "Profile saved" for some seconds and the user is sure that the changes are save and sound.
In case I msissed somthing let me know.
I have tried both solutions and #2 is the only one that worked for me.
ASP.NET MVC noob here
I was writing a quiz application where a user can select her preferences (e.g. difficulty, number of question etc.), and once she hit a submit button - she got a new page with questions.
The preferences are represented as a "Preferences" object, and the questions are IEnumerable of Question.
This all worked well.
Now I decide both parts should be in the same page - and I don't know how to accomplish that:
Should I have a new model class that is a composition of these two parts?
And also - How will I make the "questions" part appear only after the user completed filling up her preferences and clicked a button?
Should I use AJAX?
I also read a little about partial views and RenderSection.. But I really couldn't understand which approach is the most appropriate for my scenario.
So how should I draw two parts of a page, where the second is only displayed after the first is submitted?
Thanks.
How familiar are you with AJAX? If I had to guess I would think a good way to do what you want to do is to have an AJAX call which is linked to an action when the user submits their preferences. The action can then return a partial view which you can have appear on the page without a reload via AJAX.
