Lots of people recommend to wrap the MVC JsonReturn result in a textarea to play nicely with jquery forms etc.
That part makes sense but how do I get the json object back in my client jquery code?
The client jquery plugin should look something like this:
// Doesn't work since data is "<textarea>{"error":true,"msg":"foo"}
I'm working with an MVC1.0 web app and I've found a bit of an odd anomaly.
I have a search box on the first page (normal text box) and the input from this is passed through to the ViewData and on to the second page.
On the second page, I render a TextArea with this search input text from the ViewData.
Eg:
[Code]....
The problem is, there is an extra line break in the TextArea, just above the original text.
Stranger still is that if I now submit this page and the view is reloaded (after validation fails) - the original string of text has been trimmed and has no line breaks, but the TextArea now has 2 line breaks above the original text.
This can be repeated - every time the page reloads it has another line break.
It's driving me insane - does anyone have an idea on how to fix this?
FYI, you can check it out yourself - on your mobile phone, browse to [URL], punch something in the search box and hit search. You'll notice one line break added the first time the page loads. Then just hit "Find Best Offer" without entering a budget or selecting a category, and you'll see what I mean about the additional line breaks.
I have an asp.net page with a WebMethod on it to pass JSON back to my javascript. Bellow is the web method:
[WebMethod]
public static string getData(Dictionary<string, string> d) {
string response = "{ "firstname": "John", "lastname": "Smith" }";
return response;
}
When this is returned to the client it is formatted as follows:
{ "d": "{ "firstname": "John", "lastname": "Smith" }" }
The problem is the double quotes wrapping everything under 'd'. Is there something I've missed in the web method or some other means of returning the data without the quotes? I don't really want to be stripping it out on the client everytime. Also I've seen other articles where this doesn't happen.
I've databound some data to a datagrid and I'm wanting to be able to get the original data back.
I've databound the data as follows in one section of my code.
IEnumerable<MyClass> myClasses = GetMyClassesFromDatabase();
DataGridForMyClass.DataSource = myClasses;
DataGridForMyClass.DataBind();
When I've clicked a button, I want to be able to do stuff with the items in the datagrid.
How do I, given the DataGridForMyClass, retrieve the original list of MyClass?
I have a gridview that I have bound to a sqldatasource. However I have the gridview changing data shown per a drop down list and textbox so I can choose how I am searching.
My code includes changing the select command of the data source and rebinding the gridview.
My issue is that if I implement the edit button and click edit the grid view seems to resort back to the original select command that was entered when I created the datasource.
Is there any way to get the gridview to do what I want it to?
I use the JavaScriptSerializer class of ASP.net to serialize my object and return it to the client side. How can I deserialize the string using JavaScript?
View 4 RepliesSo most of the time my stylesheets appear properly. The standard/original one always works flawlessly, however it seems sometimes the mobile one is disregarded when looked at from a mobile device
I have them designated as follows:
<link href="CustomStyleSheets/standard.css" rel="stylesheet" type="text/css" />
<link href="CustomStyleSheets/mobile.css" rel="stylesheet" type="text/css" media="only screen and (max-device-width: 799px)" />
I'm using a Droid X to view the page, in portrait mode, so the device width shouldn't be exceeding the max-width specified above, but sometimes, randomly, it still reverts back to the original css page.
I have an edit page which is used from different sources. After editing I would like to redirect user to original page. Earlier I used ID (given as a parameter) and Action (hard-coded) to redirect user to certain page, but problems occurs when many different pages can access the same edit page.
Should I store complete URL and pass it as a parameter? Are there any known issues with that (string length etc.)?
The sequence of actions that I am trying to accomplish is below.
Context: user can add products to its own account.
User tries to add a specific product. (He/she is not login at this point.
In the code behind, I need to redirect the user to login page before I can add the product to user's account.
After login, how do I take the system back to the logic to finish up the action in step 1.
I have an Send.aspx page that has an uploadify control on it. Upload.ashx handles the file upload.I am adding a file record to a sql database in the Upload.ashx file and I need to get the ID of that record back from Upload.aspx when it is done.Can't get it working with Sessions. =( Something to do with an Adobe bug?
What would the best way to handle this be?Here is the uploadify control:
<script type="text/javascript">
// <![CDATA[
var contestID = $('[id$=HiddenFieldContestID]').val();[code]...
This took a while for me to figure out. But in retrospect it is extremely simple. For this reason, I mad a video tutorial to help newcomers get started quickly and understand how this awesome control works.

We have an exisiting Web Service which receives SOAP requests and returns the data accordingly. However, we have a new project which requires the same information but the Android SDK doesn't support SOAP so we need to use JSON. As JSON is just a data container format, I need to write a new module to replace the SOAP WSDL which receives a querystring from the Android app and then processes the data and returns it in a JSON packet. The problem is that having never used JSON I'm unsure as to how I return the data to the app in JSON format. Does anyone have any examples I can look at in VB.Net or C#?
View 2 RepliesI have a tag element in .aspx page:
<a id="loginLink" runat="server" class="loginLink" href="#" onclick="$('registerform').hide(); $('signin').show(); this.style.display='none'; $('back').show(); $('reg-signin-email').focus(); return false">Already signed up? Log in here</a>
and trying to get loginLink.ClientID , but it spits back ct100_main_loginLink. How do I get original 'loginLink' id in the same aspx page?
Tried var ctrl = document.getElementById('<%# loginLink.ClientID %>'); and it didnt work..
example:
<asp:Content runat="server" ContentPlaceHolderID="Main">
<a id="loginLink" runat="server" class="loginLink" href="#" onclick="$('registerform').hide(); $('signin').show(); this.style.display='none'; $('back').show(); $('reg-signin-email').focus(); return false">Already signed up? Log in here</a>
<script type="text/javascript"> alert('diplay here original loginLink ID instead of ct100_Main_LoginLink'); </script>

there are a few paragraphs separated by line feeds "
" in a textarea, say
Paragraph1 "
"
Paragraph2 "
"
Paragraph3 "
"
what i want to achieve is to process each paragraph into tag. How do you do that? (Need a server side solution) so it looks like
<p> Paragraph 1 </p>
<p> Paragraph 2 </p>
<p> Paragraph 3 </p>
On top of the complexity, if you have a blockquote there
Paragraph1 "
"
<blockquote> "
"
test
</blockquote> "
"
Paragraph2 "
"
Paragraph3 "
"
should come out to look like
<p> Paragraph 1 </p>
<blockquote>
<p>test</p>
</blockquote>
<p> Paragraph 2 </p>
<p> Paragraph 3 </p>
Let's say you have a Javascript function that calls a web service method. So that webservice completes and calls a callback function, which has the result.
How do I get that result back into the original function that called the web service method? Essentially, I'm trying to "synchronize" an asynchronous call.
Update:
This is what I'm trying to do. I'm validating based on the return value of a web service.

I have a gridview (Edit and Delete enabled) that shows a table. A Text Box and A Button. When I type something in the textbox and click the button, the button runs the datasource.filterexpression and filters out the rows. The question whenever I click on the edit button after the filter has been applied The grid auto resets back to the original table? How can I solve this?
View 1 Repliesi am searching for a way to create a grid (from some kind of jquery grid plugin didnt choose one yet)
anyway i want to call a webmethod and return a json serialized from a List of an object i created.
today i just use a regular grid view inside an iframe
but i want to eliminate that iframe and create those grids with ajax requests.
Does anyone know how to convert backend data to a json response using .NET technologies? It'd be nice to have this and use jquery to call some information on the backend.

SO I created a Panel to use to drag my modal popup, but any movement of it when you release the mouse it returns back to it's original position. What causes this behavior and how to stop it? Using Master Pages, but staying inside the content area.
Code:
<asp:Panel ID="pnlOwner" CssClass="pnlBackGround" runat="server" Width="450px">
<asp:Panel ID="pnlOwnerDrag" runat="server"><b>Select Endorsements:</b> </asp:Panel>

I have been at this for hours and am pretty stuck. I am using MVC2 with VS2010 Beta 2.
Here is my javascript from the view:

Here is my controller code:

I can set a breakpoint in the GetMember method and it does receive the Member_ID parameter correctly. It also correctly returns a member object from my repository (dpR). The function in $.getJSON call that is supposed to receive this result does nothing however. There are no exceptions or javascript errors. It is just silently dying.
I have a string I need to convert back to a date. I can call .ToString("yyyyMMdd") and get the string i want. My question is how can I convert that back into a date? I'm trying something like the following with no luck.
DateTime d;
var formatInfo = new DateTimeFormatInfo {ShortDatePattern = "yyyyMMdd"};
if (DateTime.TryParse(details.DetectionTime.Date, formatInfo, DateTimeStyles.None, out d))
{
lit.Text = d.ToShortTimeString(); //would like 07/30/2010 as the text
}
I've never used DateTimeFormatInfo before if that isn't obvious. Can someone point me in the right direction. I know I could probably use substring and create a new DateTime(y, m, d) etc... I'm just wondering since c# interpreted .ToString() correctly, if it can't derive a date from the very same string it output.
I'm trying to populate the slickGrid with an ajax call.

If I have a string containing valid JSON
how can I convert to an obect in c#?
Is there a library or something that can help to convert xml(or json) to sql? Output should be an sql script with referential integrity support, etc.
