ListBox issue

[renuami]

Hello
I have a listbox with 30 items/values and i am binding these values from database. Here is my question when 'A' is pressed automatically how can i transfer the control to the word that starts with 'A' and when 'B' is pressed control should go to the word that starts with 'B' and so on......

Please advise

You can solve this problem using ajax toolkit and web service.

Can't you just use the KeyPress event to a method that loops through the ListBox.Items and checks if it it starts with the letter pressed?

That's how I would do it in a Windows Forms application.

The O.P. (Original Poster) never said anything about needing to input text. The need was to select an item from a list of choices. Think of it like selecting a country from a list: You don't type in "United States". You hit 'U' and the first country that starts with 'U' is brough to the selection.

Ok, i agree with u. but one thing tell me, you need to some button or input any control in which you can type 'U' that word you select, If you want this way , i think , this is more compatible.

Yes, and no. You have to have a control that receives the action of pressing a key. That is not the same as having a control that *displays* the key you press. Using a textbox as the tool to have a listbox make a selection just confuses the user. The ListBox itself can react to a KeyPress if it is the control that has focus.

Or one can get fairly exotic and start intercepting the Windows Messages for keys being pressed and decide where to route those messages. This is how I handle "behavior shortcut keys" is some applications.
