assign value to combobox

[lttan123]

hi there
i am having some difficulties to bind value to combobox in windows application.

combo.Items.Add (new List("a","b"))

I have created a class.
The value is there but what is displayed is the class name. How should i display a value from he value i have keyed in. For instance i want to display 'a'

combo.Items.Add("a");

Is that what you want?

[lttan123]

combo.Items.Add("a");

Is that what you want?

nope. Well i want a displayed in my combobox. But i also want to assign a value to a . for instance 1.

so when i click on 'a' the value is 1

You need to realize there is a separation between those two things.
For 'a' to have a value, then 'a' is a variable.
For you to display something in a combo box it needs to be a string.

You may want to investigate Dictionary<>
Basically its a 2d array. You could put the key into your combobox then use it's value elsewhere in your program.

This is a bit of a nuisance with the Combobox. Basically the specs say you can add an object too to the combobox. The value displayed will be the ToString() of that object. So you may need to create a small class that holds the value and override it's ToString to return the display text.

Cool. I didn't know that one. Will have to try it some time. Thanks!

Like I said, the whole thing is quite a nuisance. Creating a class just so you can have name, value pairs.

You can use 2 combo boxes, one to hold "a" while the other will hold "1" accordingly. Then you make IndexChanged event that will synchronize those two combo boxes, so everytime you pick "a" in the first box, the second box will be "1". Just an idea to get around it. :D

Not very efficient memory and performance wise I have to say. Especially if more than one comboboxes are required. The advantage of creating that class to hold the values is that you (normally) only need one class for all your comboboxes.
