I am using HTML buttons in MVC, but is there any way to handle ASP buttons in MVC rather than HTML buttons?
No, buttons in MVC are pure html code. There is no "OnClick" event like in asp.net webforms.
There is a possibility to use asp.net webforms component in MVC (you can find some blog post if you search), but I discourage this. Stick with HTML

Hi all I did search to see for answer but nothing.
My question is related to dotvvm framework.
I have installed dotvvm into a existing mvc 5 application and work correctly
but becouse the dotvvm does not know razor markup I can't use telerik ui for mvc.
Have somebody found a solution to this problem ?
Your wolkaround or council is appreciated.
Thanks
Telerik MVC controls cannot be used in DotVVM pages right now, we are thinking about MVC interop, but it's not in the framework yet.
But the MVC controls are wrappers for Telerik Kendo UI which can be used without ASP.NET MVC.
There a nice Knockout Kendo library which allows to use the Kendo UI controls with Knockout JS. Since DotVVM is based on Knockout JS, you can use the data-bind syntax in your DOTHTML pages and access the viewmodel properties:
<input data-bind="kendoNumericTextBox: Price" />
The viewmodel looks like this:
public class MyPageViewModel
{
public decimal Price { get; set; }
}
There will certainly be some limitations and unfortunately there are no DotVVM wrappers for Kendo UI, but the basic controls can work like this.
If you have more complex scenarios (DataGrid control or something like this), you can use the plain JavaScript solution and access the viewmodel properties using the following JavaScript syntax:
dotvvm.viewModels.root.viewModel.Price()
But the viewmodel is not a plain JS object, it is wrapped with Knockout observables, so you have to unwrap everything, or use dotvvm.serialization.serialize to build plain JS objects.
The example for Kendo Menu documentation here sets the popupCollision property in Javascript. How can this property be set using Asp.Net MVC HtmlHelpers for Kendo Menu?
According to Menu Builder ASP.NET MVC documentation there is not such property. Unfortunately this differeneces sometimes happens betveen JS and ASP versions like there are two other teams of developers.
MVC HTML Helper just generate JavaScript code, so you can try set it using JavaScript setOptions on document ready:
$("#menu").data('kendoMenu').setOptions({
popupCollision: false
});
Or even better, use the javascript version in the first place if you need this property.
Do we have any Rich Textbox/Textarea options in MVC3 or do we need to use jquery RichTextbox plugins?
ASP.NET MVC has nothing to do with Rich TextArea. You will need JavaScript/jQuery for it. I would recommend using jHtmlArea
You need to use plugins. ASP.NET MVC is a server side framework which allow you to spit HTML. And in HTML you have the <textarea> tag. That's where the ASP.NET MVC framework role ends. If you want to make something more out of this textarea tag you need client scripting => so go ahead and pick your favorite WYSIWYG editor. There are lots of them.
I read that there aren't events in ASP.Net MVC.
However, I added button and when I double click it a buttonClick event was made.
So, are there events in Asp.Net MVC or not?
That is because you are using the webforms view engine. This view engine includes all the page life cycle stuff from the webforms framework. That means that you can, theoretically, use anything from webforms in asp.net mvc if you are using the webforms view engine. However, I'd strongly suggest that you don't do that. You will miss out on all the advantages with asp.net mvc and you'd be better of just using webforms in the first place.
If you are new to asp.net mvc I'd suggest that you'd use another viewengine instead as that will help you learn the framework a lot better and faster. There is a viewengine from Microsoft called Razor that you could start with.
If you're seeing a buttonClick event handler created when you double-click a button, you are likely attempting to use the Button server control. Instead you should simply include an <input type="submit" value="Button Text" /> element within a <form>. The form's action will result in the controller's action method being called on the subsequent post request.
I highly suggest that you do some do some research on ASP.NET MVC. There are several good resources, but here's a short introductory video to start with:
http://www.asp.net/mvc/videos/mvc-2/how-do-i/5-minute-introduction-to-aspnet-mvc
There are not server control events like there are in webforms. There are jQuery and javascript events that can happen in the HTML/DOM though.
If you double clicked a button on a designer canvas in visual studio, and it created a button click method in another file with a signature like public void MyEvent(EventArgs e), then you are not working with an MVC project.
I am trying to convert my existing ASP.NET application to MVC 3 Razor. I use a lot of updatepanels, and I do conditional updates at the code behind using MyUpdatePanel.Update().
I am not finding this functionality with MVC 3. I can see a lot of blogposts talking about jQuery and how to use it to achieve the same, but I want to render other partialviews from my action conditionally. Is it possible to achieve it?
The way you'd work with Ajax in ASP.NET MVC is completely different from the ASP.NET way (i.e., Ajax toolkit with server-side controls such as UpdatePanel).
ASP.NET MVC is more basic and therefore more work. You handle Ajax calls on the client side using a library such as jQuery, and on the server side you implement a controller with Ajax methods.
