I am wondering that if an ASP DropDownList Control support Multiple Selection or not?
If Yes, then how can i enabled multiple selection in DropDownList ???
No, but there's lots of free stuff on the web. Here's a full sourcecode, tutorial and example for just what you need:
Link
By native dropdown never allow multiple selection, but you can use list box instead of that, this have option to set mutli / single item selection. Other wise if you want customized one you have to use some jquery plugin or some other js frame work plugins
you can try this sample link :)
jQuery Dropdown Check List
If I got you right, then you want to enable the multiple selection in your drop down list.
Here are some references where custom controls can solve your problem:

I Want to make some dropdownlist act like a textbox without losing the ability to explore the list and i want the list to autoselect the list item that match the text in the textbox (Searchable DropDownList).
if the text didn't match any list item i want to insert this value into a lookup table.
I'm using the AutoCompeleteExtender in other textboxes but with this extender the user unable to open the list and select a specific item.
if there is a better practice i'll be glad to know it.
I personally recommend the Select2 plugin, I have been using this in most of my project which have the same requirement as you have.
Select2 gives you a customizable select box with support for searching, tagging, remote data sets, infinite scrolling, and many other highly used options.

For the searchable dropdownlist part, you can use this plug-in. This plug-in also enables you to get the keywords that didn't match any list item
How can I get my CheckBoxList to have three possible states ? More precisely, is there a way to have three possible states for each checkbox : checked, unchecked, undefined (in most GUIs this is represented as a full square).
Alternatively, do you recommend another control that would meet these needs ?
UPDATE : Ok, given that HTML does not support tri-state checkboxes, I'm looking for a way to 'CSS' (color fill, highlight, etc...) the checkboxes of the items that are in that 'undefined' state from my server point of view.
Not all GUIs represent undefined as a full square. That's why it's going to be clearer to use one of the following:
1. Radio boxes
2. Dropdown
3. ListBox
Any asp.net control you use will ultimately need to be rendered as an html checkbox, which can only be checked or unchecked. You could use a data- attribute to keep track of extra state behind the scenes, but that wouldn't be reflected in the UI.
I suppose you could also implement a client-side solution using JavaScript and CSS as well.
You could just extend or derive from the CheckBoxList and create your own custom control from it.
Here is an example of this.
Custom CheckBoxList
I have decided to use CheckBoxList anyway, since I need two states accessible by the user, and a third one not accessible by the user but to display inconsistencies.
The way I have solved this is through Javascript + CSS. Some bits of ideas here: http://css-tricks.com/indeterminate-checkboxes/
I'm new to the asp.net . I have placed dropdown list control on my web page. I want to bind image as well as text to the drop down list. The control should be unbound control.
How to do this?
thanks.
Short answer is: you can't do it with a regular dropdown control. You need to cook your own version of something similar to what telerik does with their combobox control. If you look at the HTML rendered, you notice that they achieve this by using <div>, <ul>,<li> and a lot of javascript.
One alternative could be to use jQuery for this. There's a nice plugin called ImageDropDown that does what you need.
How to this for combobox?I have long stackpanel which first it has only combobox.And when i select anything from combobox it will be added as button or other thing like on the picture.And it can be closed
[EDIT] I need anything on WPF
This should do the job nicely in WPF; http://www.codeproject.com/KB/WPF/MultiComboBox.aspx
The combo box that ships with WPF does not support selecting multiple
items...
This article describes a WPF combo box that supports both. It also
describes a list box, which the combo box inherits from, that supports
binding to the SelectedItems
Alternatively: WPF: ComboBox with CheckBoxes as items (it will even update on the fly!)
Recently I’ve come across something weird… I needed a ComboBox that will allow the user to select multiple items.
The the solution coming to mind is using CheckBoxes. I have found several examples, but neither one displayed the selected items with pretty commas like this;
i m not sure what you are asking for but you can use this.

Try this here, great combo box for ASP.

You'd have to implement your own control, because as far as I know, standard DropDownList uses browser's standard combobox and it does not support images.
You might start with http://www.asp.net/AJAX/AjaxControlToolkit/Samples/ComboBox/ComboBox.aspx
and modify it to show images
There is no such thing in an HTML select element. You would have to write it using JavaScript, e.g. something here.
