I have been struggling quite a bit to get this JQgrid to work with Asp.Net.
I found asp.net samples online...but if I modify them according to my database,it flops.
Do I need to change the DataTable to JSON functions as well?
Out of my search,I found these 2 articles getting me pretty close...
http://arahuman.blogspot.com/2009/06/jqgrid-using-mvc-json-and-datatable.html
http://www.codeproject.com/KB/WCF/jqGrid.aspx
But then,it just doesn't work if I try a sample project with my own data table.
Can someone give me a hand please?
Thanks.
For ASP.NET we have created a server-side component, with programming experience / APIs very similar to the stock asp:GridView control. Note that the server-side component is not free though.
You can see more than 30 examples of jqGrid ASP.NET here
http://www.trirand.net/demo.aspx
and download the component and sample projects.

jqGrid
Have you made changes to the GridDemo.Home.GridDemo.setupGrid to match your database columns.
Jqgrid needs the setupGrid to be called with columns and other setting as per your preference.
If you post exact problem faced someone can help out.

Im new to using angularjs with webforms.
i am using asp.net 4.0 webforms project. It have a usercontrol(uc.ascx) with a textbox and I dynamically multiple of the usercontrols on a page(Default.aspx)..on this aspx page i have a text box which should display the sum of the values in the textboxes of the dynamically added usercontrol..
can some one help me on how i can achieve this?
I researched all over the internet but could find a proper tutorial that works with usercontrols and angularjs
Well I think your are looking into the wrong direction angularJs isn't similar to knockoutJS probably both of them have double binding, but definitely they are very different.
Angular is a Single page application that's built mostly for CRUD's applications, the typical architecture is to use a restFul web service behind angular (which is going to be your front end) and they communicate using JSON as the communitacion format, been that said, I'd suggest to move on ASP.NET web API and angular
this video could be helpful for you to get the whole picture.
EDIT:
Unfortunately i don't have an specific example for your scenario but I've found a couple of articles that may help you on your journey.
A good example of how to use knockout.js and asp.net definetelly you can look at it and take that as a good source for learn it and apply it to your case.
This is another example using a usercontrol with knockoutjs
take a look to this gibhub repo with and example of the proposed architecture
Assuming I'm stuck with asp.net web forms (I'd love to use MVC partial views), are there any good alternatives to asp.net AJAX 4.0 client-side templates?
In other words, is there some way to specify some html, with placeholders for data properties, to which I could then bind a JSON result. Are there any good jQuery plugins to do this?
I ask because based on the results I'm seeing from Google, this library doesn't seem to be widely used—most search results are from 2008-2010. This question seems to confirm that suspicion.
EDIT
I despise answering my own question, but this link (jQuery Templates) seems to me to be the best bet. If anyone else has any input, please post.
Definitely consider jQuery Templates. We use them quite extensively in WebForms with ScriptServices as a data provider. There is a very small learning curve.
Also check out KnockoutJS, which integrates seamlessly.
Adam, coincidentally, I am using JQuery to retrieve some server side data calling Web Services via Ajax and binding the result on the client side. On my particular case, I am only showing data in a tabular manner, so I am using the jquery datatables plugin (which is fantastic, in my opinion; the API is well documented and easy to extend if you need to).
If you need to show data differently, I think you'll need to write quite a good amount of boilerplate javascript code.
EDIT: I just saw your link reagarding Jquery Templates and looks really cool. I didn't know it existed :) Thanks!
I have taken some text field and abd some labels and one submit and one reset button. I want to code like: when i enter some values in text boxes and click upon submit my record will get submitted into the database. And when i click upon reset then my form will get reset.
Please let me know how will i code this scenario.
Thanks,
Ashish
With due respect, this question is rather broad and you would likely be better served by doing a bit of searching for some base knowledge about the tasks that you are looking to perform.
I would suggest that you begin by going to your favorite search engine and querying for:
HTML Forms
Insert data into a database
ASP.NET Tutorials
Once you have a grasp of the basic technologies that you're using, you should find that it is far easier to accomplish your task. If, by chance, you run into any specific problems or issues, then this would be a great place to ask questions related to them. Best of luck.
asp.net and databases
http://www.asp101.com/samples/db_add.asp
resetting the forms
http://www.java2s.com/Code/ASP/Asp-Control/Resettheform.htm
you should try using google first. these examples came up on top for simple queries like
asp.net databases
and
asp.net reset forms
that said you have not really provided enough information to garner a useful answer.
what database are you using, what version of asp.net (are you even using it, or did you click the tag by accident - you
dont mention it in your post), what platform - specifically?
I’m new to .net, though I’ve been writing in classic asp for years. I know it’s time to make the change, but I can’t stand how bloated the HTML becomes.
For example, a simple menu using a web.sitemap and adds over 100 lines of JavaScript and HTML. A simple form with server-side validation adds in masses of ugly JavaScript. And a basic table of data using GridView adds in a ViewState that makes my eyes water.
Call me a purest, though I don’t like sending data to the browser unless it’s needed. And I don’t need a form-riddled menu when a simple unordered list of links will suffice.
So, set in my ways, am I destined to forgo the benefits of the Framework entirely by insisting on writing my own, cleaner code for everything? Or am I missing the point?
As a brief aside I’m a big fan of Campaign Monitor, a newsletter distribution company. They’ve written an elegant and comprehensive user-interface in .net without a single ViewState or bizarre .net-mangeled ID reference. Even the Sign Up form on their website (/signup.aspx) is as clean as a whistle. What’s their secret?
I hope I not the only one. Any advice would be greatly appreciated.
Try ASP.NET MVC or one of the other MVC web frameworks for .NET
If your GridView doesn't need it, then turn ViewState off for it.
Also, please edit your question to say what version of .NET you're using. Some of this gets better, and some does not. You might also want to try VS2010 beta 1, and complain about anything it doesn't fix.
Another idea would be to go on treating ASP.NET like it's classic ASP. Do it exactly the way you're used to, but do it with the idea in mind that there's about 10 years of development work that's gone into solving some of the problems of classic ASP. Once you actually hit one of those problems, find out if ASP.NET has solved it, and how.
For instance, I have a hard time believing you enjoy writing FOR loops to generate table rows. If you get tired of that, learn to use a Repeater control, or a DataList control, or even the old DataGrid control. If you turn ViewState off on those, I think you may find the generated HTML to be acceptable, and you'll find it a lot easier to generate tables and other structures that repeat based on repeating data.
You can opt-out of much of that bloat by not using all the out-of-the-box controls that come with it but I prefer the MVC route that activa suggested
Here is my list:
Keep the use of asp controls to minimum
Turn off Viewstate when it's not need
If you don't want the JavaScript associated with Client Side Validation (with ASP.NET Validation) set the EnableClientScript to False
Use asp:literal instead of asp:Label
Yeah it seems to be that everyone is bashing webforms at the minute for the reasons you have outlined above. HTML heavy Controls, ViewState, no control over ClientIDs all seem to cause an issue with people.
However let is be said that you can use asp.net (webforms) and produce some decent applications.
Control of html is yours through httpModules and httpHandlers and some of the issues mentioned above are fixed in asp.net 4.0
I just listened to a great podcast comparing MVC and webforms. Its in the area you are asking about. Also check out this blogpost by a dotNetNuke regarding the good asp.net code and why people should take a breath before converting everything to mvc.
Having said that I've tried Asp.net MVC and it is awesome. I'd probably look at dotNetNukes code to as its a mature asp.net product.
Also, when you do want to use these newfangled server controls, check out the css friendly control adapters. They clean up much of the bloat.
For client IDs the key thing to remember is to let the framework handle them. If you need to get an element on the client side, remember to emit the control's ClientID property into your script.
I've been using a template system and am very happy with it. Basically write an http handler for .html files and put tokens in the html files that regex could find in one sweep and inject any stuff. (google template c# for more info).
I tried some of the supposedly cool new features of ASP.NET for a little while. I also didn't like most of them. I felt constrained to work within the limitations of the common paradigms Microsoft had dreamed, even though I new how easy it would be to produce the HTML and JavaScript myself to do specifically what I wanted to do without having to learn how to jump through the hoops of so many new Microsoft-specific idiosyncrasies.
Anyway, I stopped using the parts of ASP.NET I didn't like on new code I've been writing lately. When I first started using ASP.NET, nothing in the MSDN documentation jumped out at me about how to avoid such complications, so I posted a couple "Hello, World" at http://www.agalltyr.com/rawaspdotnet.html to help spread the heretical word. I couldn't care less if it's the latest cool technology or the recommended technique. It's a reliable and reasonably efficient tool I can use to do my work.
Oh, and I'm not in the mood to learn ASP.NET MVC either. That's just more idiosyncrasies. Give me a language (C#) and a framework (.NET), and I'll design my own abstraction, thank you.
We have a requirement to increase the functionality of a grid we are using to edit on our webapp, and our manager keeps citing Excel as the perfect example for a data grid :/ He still doesn't really get that a Spreadsheet like control doesn't exist out of the box, but I thought I'd do a bit of searching nonetheless.
I've found a couple of products on Google, but was wondering if anyone else has any feedback around any such controls (obviously the cheaper or ahem freer the better)
EDIT We do currently have the Telerik controls, but what the 'current' requirement is, is a control that can copy and paste (e.g) 3 cells from one row and paste them on another, the row by row editing of Telerik doesn't really cut it. We are currently in competition with an 'Excel' based solution, which is always a nightmare in winning users around, who always prefer flexibility to structure
Update: with Silverlight fast approaching, maybe you can use a real excel control.
Devexpress has a powerful grid control for both web and windows. It is not free and I guess nothing really matches Excel. But once the users started using it, they wanted every app with it. Check these videos especially the data grouping one.
You may consider 3rd party tools of native Excel functionality. There are most buzzed on the forums:
Aspose Excel Cells
ComponentOne XLS for .NET
Or Excel Jetcell .NET.
This may not be directly related to your question, but on the server side have you considered what operations you will need to perform that will mimic Excel? You may want to check out SpreadsheetGear which will give you complete macro functionality.
They have new charting features that I haven't used yet, but they are supposed to work with Asp.net.
