Show lable/text if the combo box contains only a single value - winforms

I have a combo box that contains a dynamic list of values.
I would like to do this:
if there is only single value - the combo box will be displayed as text only (maybe: will be replaced with a "label" or something similar) and will not give any choice but will only display.
What is the easiest and most convenient way to implement this?
Thank you

Codename One ComboBox how to highlighting already selected value

We are able to create ComboBox and populating data too. But we need to highlighting already saved values. Can you please suggest code for this.
Our requirement is if Combobox has 1,2,3. If I select 2 and save. We need to set the combo box value 2 in such way that when we open the Combobox need to display this 2 as highlight value along with 1,2,3 values.
Simply same as select box option selection.
I would generally recommend avoiding ComboBox altogether.
Assuming this isn't an option you will need to define a renderer and disable the OS specific 2 render mode using a theme constant:
otherPopupRendererBool=false

MS Access Search Form need to pass values from unbound combo box to query

I have a very simple table with about 10 columns. I have set up a search form with all unbound fields and a couple of combo boxes that reference the table on 2 columns, one for each combo box. I have been using this for these two types of criteria in my query:
1) Like "*" & [Forms]![Contract Search]![ContractName] & "*"
2) Like IIf(IsNull([Forms]![Contract Search]![Amount]),"*",[Forms]![Contract Search]![Amount])
Basically i have the first one setup to match anything in the text box and if left blank return all. The second one I have setup to match exact or if null return all. I want to use the second criteria logic for the combo boxes.
This works fine for the text boxes and check boxes but when I use the same format for the combo box it doesn't display anything on the query.
Combo Box Criteria I am using:
IIf(IsNull([Forms]![Contract Search]![Project]),"*",[Forms]![Contract Search]![Project])
even a simple criteria:[Forms]![Contract Search]![Project] does not work with the combobox.. if i convert it to a text box it works..
The values show up fine in the combo box in the search form, but they dont seem to pass the selection to the query. I dont understand what I am doing wrong. These are all unbound controls. I am using Microsoft Access 2010.

How to dynamically change the combobox values based on another combobox value?

I have multiple combo boxes which should be inter related. I need to change the combo box values based on a value selected in one combo box.
Say, If I select one Category in combo box, then all the other combo boxes should be getting values which are related to Category.
Please have a look at the table below:
If you have a lot of values ​​in your combo-box, it's not necessary to early load all.
You can fill them "manually" by a "querymode : local".
So, your query who fill your combo should depends on the others
Each combobox needs to be assigned a store .
In your case, you can create one store with only Categories data and another store with all the data shown in your grid one for each of the dependent combo boxes.
Using onselect event listener of Categories dropdown, you can filter the stores of the dependent comboboxes.
(If you want to know how to define a combobox and store, you can look at the below example
http://try.sencha.com/extjs/4.1.1/docs/Ext.form.field.ComboBox.1/
and several others from sencha docs.)

ListView with Checkboxes and Editable Fields?

I have a ListView form that looks like this:
How do I make it so each cell is like an editable textbox so the user can edit the values by clicking on a cell? Like if they click on "Count" a text edit cursor should appear in-place and they should be able to type to change the value of the field (Not in a separate dialog box or text field)
The ListView is intended for flexible display of a list of items. Similar to windows explorer's ability to show icons, thumbnails, details and basic list, all from the same set of objects. If you really want to edit all of the elements in your data objects, you should probably read up on DataGridView and data-binding.

Does anyone know of a good load-on-demand combobox for WPF?

I have been searching for a while now, and have not been able to find a load-on-demand combo box that populates itself depending on what is typed in the combo-box.
I also have a requirement that an item in the list must be selected (i.e.: free text can be entered but not "selected" - only a "search result" can be selected from the list in the combo box.
The scenario is as follows : there is a text box/combo box where someone enter the first 2 or 3 characters, a web service is called which queries a database and then populates the combo box.
Are there any controls or code example that anyone knows of? Or alternatively another way to implement this?
Here is a link to an asp.net control that has this functionality:
http://demos.telerik.com/aspnet-ajax/combobox/examples/populatingwithdata/autocompletesql/defaultcs.aspx
use the event "textchanged" to dynamicly add/remove items :)
updated :
why not bind the results to observable collection and databind that to the combo box , so on chnage > query database > bind items to the collection , .net automatilcy updates the items , this might work :)
Telerik combobox with autocomplete will be what you are looking for.
