In my combobox has following

tableno
1
1-1
1-2
1-3
1-4
2
2-1

I find the Preferences from database table which is equalent to entered tableno

The user may be selecting or typing on the combobox. So I give the query for Textchanged event. But the problem occured everytime type the text, the Textchanged event is calling.
When I type 1-1, three times the event is calling, So three times the error msgbox is displays. So please anybody help which event is suitable for this problem.

I think the SelectedIndexChanged event is more suitable for this purpose as explained here

Apparently it is more suitable, a 5.

Here the problem is that textchanged even accures each time you change the text of combobox

so for this
you can move your code to key_down event and you can execute your code on press of perticular key
say enter key
like this
if (e.KeyCode == Keys.Enter)
{
your code goes here
}
in this way your code will execute only when you will press enter key
