AJAX :: Jquery Dialog Box + MVC / How To Pass Some Elemet [id].val Into ModelState
Feb 23, 2011
I send to my view via a ViewModel few List of entities
[Code]....
My view contain a form to create a futur object "Skill"Inside of it you will have a dropdownlist of "Categories" My dialogBox is used to Add or Edit these Categories.I use Ajax to submit the CategoryEdit form to the corresponding Controller.
[Code]....
[Code]....
Unfortunatly My controller lost all of my ViewModelState and can't find any argument.
My controller:[Code]....
I really want to use the dialog box offer by jquery. I just need to know haw to pass some elemet[id].val into my ModelState.The thing is when I open this dialog box and check with firebug "View form Information" It finds only the element from the previous page (I mean the Skill Form).
After wading through quite a few articles on creating modal forms (using partial views and jquery) I got things working fine for my login....as long as you enter a valid login though!
What I did:
Created a partial view containing my login form.
In my action controller, the get action just return a PartialViewResult, which get dealt with by a bit of jQuery in my master:[Code]....
Like I said this works fine. Now the post action of my login check if it's a valid login, and if so send the user to the passed returnurl or the home page.
However, if the validation fails, I now return the partial view again, which work , but the partial get displayed by itself instead of rendering in the modal form that was opened by jquery.
I have a requirement where i need to show the list of data in a jquery dialog once a some link is clicked .I can easily collect the data that has to be shown in the dialog on page load and display the data in the dialog.I will place those data in a hidden div and simply pop it up when the user clicks on the link.But my requirement is that there has to be jquery ajax get when the users clicks on the link and that content should be displayed in the jquery dialog.How can i achieve that.
I'm using the ASP.Net Validation controls and I want to display the Validation Summary in a JQuery Dialog instead of the native javascript alert messagebox. I've found this solution (aspsnippets) by overriding the clientside WebForm_OnSubmit() function:
The WebForm_OnSubmit() function is being rendered by the BaseValidator control and in the form tag te following attribute is being added:Â onsubmit="javascript:return WebForm_OnSubmit();
I am running into a problem on a page which has an UpdatePanel. The input field with the validator (1 to make it simple) is in a Panel within an UpdatePanel. The Panel is set to Visible=False at the first Page Load. There's a button inside the UpdatePanel which makes the Panel with the Validator Visible.
When this happens, the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag are not being rendered because it's an AJAX callback and the form tag is outside the updatepanel (in a master page), so the validation summary will not be shown in the jquery dialog.
Validation is being performed, so the validation summary wil be shown in a div on a page, but the validation is not being called by the WebForm_OnSubmit() function in this case, because it's not being rendered.
So, when the validators are not visible at the first load and they will be made visible by an AJAX callback, the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag are not being rendered on the pag. Because of that, the WebForm_OnSubmit() function will not be called and the validation summary will not be shown in the JQuery dialog (although it is being shown in a div on the page). How can I get the Validation Summary to be shown in de JQuery dialog in this case?
Is there another function that has to be overriden for this case? I know I can use a Full Postback for the New button and then all the stuff needed is being rendered on the page, or I can make the panel not visible by using a style, but I don't prefer that because there are a lot of pages with this situation.
One solution is to use a dummy textbox with a dummy validator (with a dummy validationgroup) of which I set the display to none. Then this dummy validator will cause the the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag to be rendered.
I'm using ASP.NET and attempting to call a method with a signature of
[WebMethod] public static string GetInfo(string id){...}
using the following javascript:
var elementValue = $("#element").attr('id');
[code]...
And this is not working.If instead I set elementValue = 2; it works fine. If I try to hardcode in a string value for testing purposes e.g. elementValue = "nameToLookUp"; It fails.Why is this happening, and how do I resolve it?On a side not, why is type: required to be POST instead of a GET? In the end I just want to pass a string value I want to look up in a DB and retrieving some json data.
I have the following jQuery event that gets fired every time an anchor is clicked. How can I pass a asp.net control (lets say a panel called "pnl_info") as one of the parameters, in addition to the "target" parameter i'm already passing?
I load an aspx page in iframe inside a jQuery UI dialog to update some data, and after dialog is closed I need to update an updatepanel in parent page. how can I do that? to be more specific, there is a datagrid in parent page and after I edit data in a dialog modal iframe, I want to update the row in datagrid.
As it is now I create a JavaScript object and then stringify it, put it in a hidden textbox and my code behind can read this string. I then use JSON.NET to parse the string which works fine. I now try to use ajax to post it to my web service but have some issues with how to send the string. I have tried many ways but gets the common errors like
Invalid JSON primitive: myString.
So I checked this out [URL] and it works with hard coded values but I want to use a variable.
JavaScsript to create the object:
for (var i = 0; i < results.rows.length; i++) { var row = results.rows.item(i); var customer = new Object(); customer.id = row['id'] customer.name = row['name'] var customerString = JSON.stringify(customer); $.ajax({ type: "POST", url: "synchronise.asmx/synchroniseCustomers", data: "synchroniseCustomers: " + customerString, contentType: "application/json; charset=utf-8", dataType: "json", error: function (xhr, status) { alert("An error occurred: " + status); }, success: function (msg) { alert("success"); } }); }
WebMethod:
public void synchroniseCustomers(string customerString) { JObject o = JObject.Parse(customerString); string id = (string)o["id"]; string name = (string)o["name"];
If I use data: '{ FirstName: "Dave", LastName: "Ward" }'
in the example above it works but I wish to pass on a string instead.
I was looking at using the Jquery request to call a second aspx page which either inserts or selects records from the database. My concern is the security of using Ajax. To pass information to the second page the Ajax request constructs a query string which is read from the second page. However, I don't know if I feel comfortable having the query string parameters so easily accessible. Especially if inserting records using Ajax anyone could follow the page being pointed to and then just load that into a new window with the query strings filled in.This would result in potentially a database attack adding many fake rows.Are there any security measures I can put in place to keep my Ajax secure or preferably hidden?
I´m using jQuery to make the ajax calls to web services. I´m not using json, I want the information in XML. If I don´t pass parameters and I make the WS parameter less it works but if I want to pass a value as parameter (I tried int and string) it doesn´t work. Here is my code:
jQuery: [Code]....
The web service
[Code]....
The error that I get from firebug is an exception System.InvalidOperationException and it says that the parameter region_id is missing.It can´t be very difficult because it works without parameters but all the information I find in internet
im using jquery. is there any way to broke the Dialog popup as diamond shape or any other shape?and how to provide minimize and maximize buttons on the dialog?
foreach (var issue in data.GetRuleViolation()) { ModelState.AddModelError(issue.PropertyName, issue.ErrorMessage); }
But at the client side I am not able to take the benefit of ValidationSummary as the call is being made by AJAX. What is the right approach on validation.
I want to know, if its possible to pass collection between pages. I mean to say i have a client-side JavaScript modal dialog on which I want to use my collection. Earlier I was using Session[] to share the value, but its becoming evil for me, as it always displays the first value. Any change in value in not updated.
So whenever my pop up is displayed I want the collection to get moved to the Child dialog. From there, i will extract the Collection, do some stuffs and again return it to parent page, preventing postbacks and session management.
I have create a web page having dynamically created text boxes if i select value in dropdown list,text boxes auto generates .but i want to save all text box values in SQL server database after clicking on submit button using ajax/JSON request
I'm assigning a div containing an ordinary grid view to the content of a jquery dialog, but the gridview is omitted from the dialog. I've tried even building the dialog fresh on a button click in case it's having a hard time binding to the data-refreshedgrid. No Joy.
1) open a dialog from using Jquery2) fill up the form and send the data from the form to controller3) if success then close the dialog and refresh the gridview from the calling page, and if not success display the error message on the dialog for
Perhaps someone out there can help me understand what's going on. I'm using jQuery UI dialog() to display html partials in my project. When a user clicks Add New it displays the add client form. However, when the user clicks on the Add or Cancel buttons in the dialog I get an error, "$(this).dialog is not a function". If I remove the open event and display a static form in the dialog the buttons the work fine.
