I try to use the jquery + json to get all elements in form and build a JSON var to post in a ASP.NET MVC method.
[Code]....
It method get all fields in a form and build a JSON, but it dont put JSON inside JSON.
Example:
If i have the follow form:
<input name="person.name"><input name="person.age"><input name="person.address.street">
The serialized string build a JSON like this
{ "person.name": "??", "person.age": "??", "person.address.street": "??" }

I have a text file named gisQuery129.json that is created using Json.NET - [URL] There is an example on how to create a JSON file and I have done that successfully, but I want to read the file on a page load event and add the values to .NET textbox controls for input values in a query. The created file looks like the following:
{
"myData": {
"randomNumber": "129",
"Application": "MyMapApp",
"FeatureId": "ALL",
"Feature": "ALL",
"spatialQuery": "FEATURE_ID= '11111' AND REQ_SEQ_NUM= 1 AND RAND_PARAM= 129 OR FEATURE_ID= '22222' AND REQ_SEQ_NUM= 2 AND RAND_PARAM= 129"
}
}
I want to read the data in the above sample JSON data and then populate my textboxes something like this:
txtRandParam.text = "129"
txtApplication.text = "MyMapApp" and three more text boxes after that.
I want to retreive the data from database and assign it to dropdownlist. For that I'm using the following jquery in the onclick event

View 4 RepliesIn my javascript code I am getting json string from cs file
var tmpString="<%=resultset2%>";
In cs I am concatenating strings to build json string. Here is an issue the json string is returned as a string and it has " with it.
"[{id:'1',name:'Aik'},{id:'2',name:'Aik or Aik'}]"
Because of " in beginning and end javascript code treat it as a string.

For Each CompanyRow In newdt.Rows
CompanyDetails += CompanyRow(1) & " " & CompanyRow(0) & "<br/>"...
How can I get this to see the GetInfo as declared..... since its in a loop within a loop?
I've been tasked with implementing a JSON feed on an asp.net website that will be consumed by 3rd party apps (such as IPhone, Android, etc) and I'd like to follow best practices.
An example of what I'd like to achieve would be something similar to: [URL]
I've chosen the JSON.net api as this seems to be highly recommended.
My Google-fu must be failing me as I can't find a single full example code for an Asp.net web application with JSON.net implemented on it, so I've no real concept of where to begin.
My question is fairly simple:
Should I create this sort of feed as an ASPX, or ASHX file? Or even a .NET Web Service? (Remember that the tools that will be using this feed are on external apps like IPhones, etc)
I created a test feed in both ASHX and ASPX format ... here is the code (I'm using Subsonic to populate the collection) ... are either of these along the correct lines?

View 1 Replies I have nested gridviews, in the outer grid I am displaying the question and in the inner grid 4 options are displayed in radiobuttons. I have kept Lock Answer button inside Item Template in inner gridview , so this button is coming with each and every question and when i click on Lock Answer button in front of any question, its saving the corresponding answer in the database. For ex, if there are 10 questions this button is coming with all the questions, all the questions are on single page and all are multiple choice. Now everything is working mine, my requirement is that I need on 1 common Lock Answer button at the bottom of the page and not with all the questions. And when I click on that common button it should run for all the questions that are displayed on the screen at should fetch and update each unique answer corresponding to that question in the database. Below is my code:
<asp:GridView ID="gvouter" runat="server" GridLines="None" AutoGenerateColumns="False"
AllowPaging="false" OnRowDataBound="gvouter_RowDataBound" Width="100%" OnRowCommand="gvouter_RowCommand"
OnPageIndexChanging="gvouter_PageIndexChanging" >
<PagerSettings Position="Top" />
<Columns>
<asp:TemplateField>

i want to receive some data from my database and in a while loop. i use this code in the while loop
Code:
Dim sqlda As New SqlDataAdapter()
sqlda.SelectCommand = New SqlCommand()
sqlda.SelectCommand.Connection = con
sqlda.SelectCommand.Parameters.Add(paramar(0))
sqlda.SelectCommand.CommandText = "select images,creationdate,dimosieyseis from t_accounts where UserName=@un"
Dim ds As New DataSet()
sqlda.Fill(ds)
if i open and close the connection it becomes slow. if i use a general con and not open and close it then i receive an error
"There is already an open DataReader associated with this Command which must be closed first. "
then i tried to resolve this error with
MultipleActiveResultSets=True that resolves the problem but it is not faster because i think it does the open and close of the connection automatically

I'm using asp.net list control that creates a table with <div> elements that have a picture thumbnail, and when the user clicks on the div and it calls Ajax method and populates a shared dialog with correct information, and then shows it to the user. In order to do this the div needs to know the item id associated with it, so it can do the db lookup.
how do you dynamically store data to a div item in a list view loop.
so something like
<listControl>
<ItemTemplate>
< div>
stuff
thisdiv.data(<% Eval(id) %>); // <-unsure about this part
</div>
</ItemTemplate>
</listControl>
