Hi,

this is used in the buttons event handler that can be set via attribute OnCommand. Then in the event handler you can access the parameter of type CommandEventArgs and inspect the value e.CommandName where e is the name of the CommandEventArgs parameter.
It can be used to have one handler method that does the work for more than one button or different jobs depending on your program flow.

Please read the example the following link points to, it's pretty clear:

Cheers,

Manfred

I've read that, thank you.
But still not for me. When i explore about the commandname in msdn i also arrived at there. but not the thing that i want.
in the example showing that e.commandname submit doing something. that is the thing that i want to know from commandname Login.
but i also have considering that my question might be quite sensitive since looks like the logic behind that commandname "login" is not open.

So if anybody out there know that it is a "closed logic/code" please inform me. :)

If you have acces to the code behind files for your application search it for LoginButton and look out for places where event handlers are getting hooked up especially OnClick and OnCommand. If you don't have access to the code behind files ... lots o' luck pal :)

Hi
After I start browsing my asp.net code
<asp:button runat="server" commandname="Login" text="Log in" xmlns:asp="#unknown" />
in html it appear like this
<input type="submit" name="ctl00$MainContent$ctl00$ctl06" value="Log in" önclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$MainContent$ctl00$ctl06", "", true, "", "", false, false))" />
I can't understand how it works. Can anybody explain this?
Thank you.
