As far as I understood your code, you're trying to bind every Row's Combobox. But the fact is, its only one combobox associated with the column. So if you bind the combobox it will be same in every row.

first there are 2 buttons on the right-bottom in every message you post. One called 'Edit' and the second one 'Delete'. So if by mistake you posted 2 same messages you can use 'Delete' and to edit the message you can use 'Edit'. Simple as usual Wink | ;)

split the string with ' '(space char, e.g. string.split(' ')) and then iterate all the splitted parts, rip first 3 or 4 chars by using string.Substring() plus keep append a main string.

There's a one-liner for everything. Wink | ;)

words = string.Join(" ", words.Split().Select(s => s.Substring(0, 3)).ToArray());

Despite everything, the person most likely to be fooling you next is yourself.

Never. It's an extension method, and it's in the IEnumerable<T> class.

so its a LINQ thing, listen mate. I use .Net Framework 2.0 usually as most of users do not have 3.0(+).

Listen mate, it's just a one-liner. If you don't understand it, it only means that you have more to learn...

How can I push a button virtual?

If you need first three characters of each word, then you use Split and Substring.

In the example you gave, you have taken "Desk" from desktop ie 4 characters and 3 characters from others. The number of characters to be taken from a word is not fixed. It depends on the word. Now if the string changes to say "Development Web Development Multimedia Development". How do you want this to be divided?

As the subject is saying, is it possible with C# to push a button like ENTER-key virtual?
Just like with InvokeMember("click"), then I just need it to do a virtual push at ENTER-key.

Hi,
The Button class has a PerformClick method.

Hmm, and how can I then use it to make a push on Enter at my keyboard ?
As I see that class, it only can perform clicks on buttons on the application.
What I want is to make a program that for examples makes a virtual push on A,B,C,D,E,F,G on my keyboard

If you have code that does something other than handle speific UI elements in the Button Click handler, you really need to move that code to it's own method. Then you can call it from both the Button Click handler and from anywhere else in your code without having to resort to funky workarounds like this.
