Hi everyone
I have the problem with my event function "selecteIndexChanged" :
when I selected an item in the combobox, this function(selecteIndexChanged)
is executed several times, then it take long time.

Please answer me fastly

Thanks so much

Hard to tell without the code written in teh event handler.

You might be re-selecting some combo item Again in this event Handler.

Remeber, If you select some item in the coombobox programatically from its
SelectedIndexChanged handler, this handler will get called again causing
un-intended recursion.

In addition to rawcoder.

The selectedindexchange fires when there is a change in a datasource. that
means that it fires more times at load time of that datasource.

Mostly is that protected with a "switchLoaded" which is set to true when
that is done, and evaluated in the indexedchange event.

I hope this helps?

1. You need to tell us what is not behaving as you expect. Your text is
very hard to understand. In particular: "i m code also write but ,one
value match to every combo selected item".
2. Your code seems to be missing a creation of a connection object.
3. Your routine looks like it handles cmbCtime (a combobox) selected
index changed event. You reference cmbTime in our SQL statement. Those
are two different variables.
4. Put Option Strict On at the top of your code.
