Jquery - Return HTML Or Data From The Server - ASP.NET Webforms
Dec 8, 2010
I am working on a page that has multiple sections and each section looks 'almost the same'. Having said that, I want to build the HTML on the server and render it for each section on the initial page load. On subsequent actions, I would do a ajax call and have the server return json data.
The other option is to 'hardcode' the HTML on the aspx page and have the JS do the necessary customizations for each section. The third option is to use an UpdatePanel and do everything server side.
Based on what should I be choosing what approach to use? What approach would you use for a page like this (think of it as a large page having sub sections on it)
Edit: One section has HTML such as user's name, and a table where users can add dependents. Another section is almost the same except its for a 'contractor' so there's additional HTML such as previous work history, but this one has name (readonly) and a table to add dependents just like the first one. Other sections have more or less the same HTML. A user can delete dependents as well, when that happens, I need to update the database and update the section to reflect one less dependent. I was hoping to make any subsequent actions as ajax calls that interact with the server and the database
which returns <div>here</div><script language=javascript>alert('');</script> The content gets loaded property, but no alert. How would I get a javascript routine to work from an ajax call along with posting the HTML code?
I have JQuery confirmation dialog function that called by server side code (C#)how to get its return value of that function? in this case the return value would be either Yes or No.I called it in button clicked event as below:
Code: protected void btn1_Click(object sender, EventArgs e) { string message = "Message from server side, please select yes or no"; ClientScript.RegisterStartupScript(this.GetType(), "Popup", "ShowConfirmation('" + message + "');", true); }
my question is how to get JQuery return value, in this case the return value would be Yes or No?
In ASP.Net MVC action methods can return json objects simply by returning something like so:
JSon([whatever])
How do I return a JSon representation of say List<String> with webforms either through a service or through a method in the code behind of an aspx page? This seems incredibly confusing compared to ASP.Net MVC.
I am trying to send data from text fields created on the client side (via jquery). The problem is the data from those text boxes is not being post back ( I'm using asp.net webforms)
I have used fiddler to view the post back data and it isn't there for those generated text fields.
I'm surprised no one figured it out. I was switching from server to non server controls I forgot to give the non ones a name field..........
At first, I should confess that I am not sure if it is a good practice or not. I have came out with the idea due to my practice of jQuery.ajax().
What I want to achieve is depended on this design:
//Server Side; an .asmx file contains a method like this: [WebMethod] public string NewContent(string parameter) { string renderedHTML = string.Empty(); switch(parameter) { case ("person"): // create an asp.net panel with // some controls in it that has form elements to enter person data // render control and assign its html to renderedHTML break; case ("department"): // create an asp.net panel with // some controls in it that has form elements to enter department data // render control and assign its html to renderedHTML break; } }
And from the client I want to do this:
// Some html in the page <script type="text/JavaScript"> jQuery.post('ajax/myWebServices.asmx/NewContent' function(returnedPanelContent) { $('.result').html(returnedPanelContent); }); </script>
Question is:
How can I make it work? Briefly to have a webservice method that returns different asp.net Panel control content created programmatically so that I can get this control rendered as HTML in my client-side and insert it to my web page?
In my asp.net website I need to return data obtained from DB by adding html tags to it from a server side method,just like a webmethod returns jsonified data. I am having trouble understanding if a webmethod can serve the purpose(i.e., htmlifying the data).If not how do I acheive it?
i am new in json script.am trying to convert the database table value into json using asp.net with c#.here, am also send the response to asp.net client side.but am not receiving any response from server side.
I am trying to retrieve asp.net C# List method in JavaScript by referring Send-and-receive-JavaScript-Array-to-Web-Service-Web-Method-using-ASP.Net-AJAX ..My Code as below
Javascript
<script type = "text/javascript"> function GetAllSVGData() { PageMethods.GetSvgElements(OnSuccessSVGElements); } function OnSuccessSVGElements(response) {
[code]....
My problem is JavaScript function OnSuccessSVGElements is not firing. When I put breakpoints in it is working fine in C#. C# Method Working But Alerts in javascript not working.
If I use jQuery AJAX to call a specific ASP.NET page method how to have that method return a value back to the AJAX method that called it?
Update
My situation is I have an existing web application with many existing methods. I would like to be able to use jQuery to execute some of these methods and then update the UI with the results. My mandate is to stay away from ASP.NET AJAX and stick with jQuery. Management is concerned about continued development and support with ASP.NET AJAX from Microsoft. I agree with them.
I'm a new comer to the asp.net world. I hear a lot about asp.net mvc and it's advantage over webforms about the ability to customize the markup and css. I also heard that asp.net is much easier to learn than asp.net mvc so I decided to go for asp.net and webforms. My question is: what's the level of customization a web developer/designer can get with webforms concerning the markup and css?
I have the following code where the function codeaddress geocodes the text feild value and returns geocoded value , geocoded value is stored in variable example ,how will i return the variable v2 to the function call and post to asmx webservice.
I have a span control which I am filling using Jquery. At the page load I want this span say id1 to be invisible and depending on some conditions I am making it visible via jquery itself.
When I make id1 runat = server and try to access id1 from codebehing, then I get an error in Jquery.
Hence I need a way to make id1 invisble at the load time itself.
I have already set id1 = invisble in HTML, But still I see this control on the page till the time jquery fills the entire data.
I need to render a few DropDownLists on my page, allowing the user to select different Categories & Locations so as to return different result sets based on their selection.
However, I want each of the resulting selections to be crawlable. I know I could just render every possible Category, Location etc as standard HTML links on the page, which perform a GET request to the specified URL, but if possible I'd like to contain all these options within a DropDownList to keep things less cluttered.
If I were using MVC I would consider wrapping that small section of the page in a GET form, with each ListItem value being the destination URL (though I wonder if even this approach would be properly crawlable?).
I am using Web Forms though and am just having trouble trying to come up with a solution.
I have an update function in my data layer which is defined as:
public int UpdateRBTable(parameters ...) This calls a SQL Server Stored Procedure to perform an update function on the database.
The process does its job for updating the table. However, the stored procedure has a return value (which indicates how many rows were updated), but this return value is not returned to the application. The application always shows that a zero was returned from the stored procedure.
What I'm looking for is a good sample of an open source WebForms site which contains demonstrations of some best practices, design patterns etc. Just want too look how experienced people apply their knowledge to build websites which can be shown to everybody without shame :)It would be good if the samples show these technologies: IoC, Entity Framework, Unit testing (with mocks), jQuery. The small samples which demonstrate the particular technology are useless as I've already examined many of them.My goal it to improve the existing huge WinForms application, so I'm not interested in ASP.NET MVC for the time being
I have started using jquery in one of my new asp.net webform application... I want to display a success message after an insert on a button click event... Here is my link button..
