Create an ASP.Net ComboBox with LoadOnDemand - asp.net

Does anyone have code or know how to create an asp.net combobox with LoadOnDemand functionality?

You can always use ASP.NET AJAX Web services to stream the data, then populate the drop down with the items by adding items to the select element.

I think this link would look good for you...

or alternatively, you may have a look at the ASP.Net AutoCompleteExtender for such a functionality. Sample here...

Fill controll type Menu using ASP.Net MVC

is there any way to fill a controll type System.Web.UI.WebControls.Menu with data from database if i use ASP.Net MVC?
If yes how can i do this?
Fill? Probably.
Use effectively? Probably not.
WebForm controls are built around the page lifecycle and viewstate. MVC has neither of those.
You could accomplish something similar by using a Partial View for your menu and create a ViewModel to populate it - just populate the ViewModel with your data from the DB. But otherwise Jfar is correct.
I'll get some links if I can - currently on my phone. Hope this helps some.

Drop down List Filter with ASPX , AJAX controls,or JQuery?

I am looking for a filtering mechanism, as the user types in the drop down box I want to filter the list to the list items that match what the user is typing. Is there any premade control for this or does anyone know the best way to achieve this feature?
Thanks
Well, that's the simple solution. The Ajax Control Toolkit AutoComplete Extender comes in handy if you wish to accomplish this. You may also have to implement a small Service.
Check it out and you will tell us.
The Ajax Control Toolkit has an auto complete extender (http://www.asp.net/ajaxlibrary/act_AutoComplete.ashx).
JQuery has an auto complete feature in the UI core (http://jqueryui.com/demos/autocomplete/).
Others built into third party tools.

What is the best solution for displaying data in ASP.NET MVC?

I am new to ASP.NET MVC and I want to know your opinion about what is the best way to display some data from database using a <table>... an ASP.NET control or a jqGrid?
In which situation must each of them be used?
I appreciate any tips. Thanks.
If I understand correctly, the MVC model doesn't support the server-side event handling of standard asp.net controls, so I'd say that the jquery grid is definitely the best option.
Asp.net controls cannot be used in asp.net mvc.
The best way is to create a ViewModel classes and declare View as strongly typed.
I could continue but unfortunately don't know what exactly do you need.
Do you mean ASP.NET Controls or ASP.NET MVC Controls?
ASP.NET Server Controls should not be used in this framework... or rather, you should not use anything that relies on postbacks and/or viewstate. There are tricks to get some to work, but YMMV.
If the control is an ASP.NET MVC Control, that's a different story, and it will work ok.
JQuery controls also work since they are javascript controls.
use the MvcContrib grid. it is working fine

Draggable Columns in ASP.NET GridView

Is there any open source that extends ASP.NET GridView, which allows Column order to be changed after it's rendered, raises a server side event when a Column is Dragged & Dopped ? I should be able to do this myself. I am wondering If there's any already.
Also, am just curious How long would it take for you to get this feature implemented.Just to know where I stand.
The GridView in .NET 3.0+ supports this feature, are you tied to an earlier release?
Component Art's grid has this functionality, but it s not open source
try jquery based flexigrid

ASP.NET message box

I am looking for a custom control which could enable me to call message of following type.
http://extjs.com/deploy/dev/examples/message-box/msg-box.html
Is there a control which function like a .NET desktop application messagebox?
I know, exactly similar may not be possible but main features I am looking for here is returning value of clicked button and custom value entered by user in code behind.
I have also started working on it myself, but hardly any luck so far.. any direction in this case will also be very useful.
There is a good tutorial which could help:
Create MessageBox user control using ASP.NET and CSS
And here combining it with the AjaxControlToolkit:
ASP.NET Popup Message Box User Control
I hope this helps!
Have you looked at the AJAX Toolkit? It doesn't do all the things you want, but it should be too hard to the extender and controls needed into a CustomControl and create your own DLL.
use the namespace "System.Windows.Forms" by adding the reference to the solution explorer
