Programmatically adding javascipt code in c#

I have a serious problem with adding javascript event programmatically.

   protected override void Render(HtmlTextWriter writer)
        {
            Attributes.Add("onkeypress", "WebEnumComboBox_OnKeyPress_" + ClientID + "(event)");
            Attributes.Add("onkeyup", "WebEnumComboBox_OnKeyUp_" + ClientID + "(event)");
            base.Render(writer);
        }

is my code, if i wrote this code, mycombobox does not see both events in clientside. Bu if i change
" Attributes.Add("onkeyup", "WebEnumComboBox_OnKeyUp_" + ClientID + "(event)");"

to

"Attributes.Add("onkeydown", "WebEnumComboBox_OnKeyDown_" + ClientID + "(event)");"

it works but, working one does not match my needs. The other (not working) one match. Please help, i want the non working one working but how?

I am sorry that I am not familiar with javascript enough to be much help, but it sounds as if the event is not allowed to be processed further. There is probably something that the event handler does to indicate whether the event has been processed, and your code is probably saying it processed the event and that the event should not get further processing when it should say it did not process the event and that the event should continue to be processed.

No problem is this. When i register two javascript events (onkeydown and onkeypress ) programmatically to my aspx page, it works. On the other habd if i try to use two javascript event (onkeyup and onkeypress ) onkeyup does not work?

One thing to check is case. Case sensitivity can be a very elusive problem. Based on the code you posted, case is probably not the problem, but in case case (I just had to say that so that I use the word with two definitions) is the problem, check for it.
