How to put multiple events code in a single event

Question

Hi all,
I am coding an c#.net application, where i have multiple events for multiple buttons. Now, I wanted to put all that code in a single event and i have to work as it was working previously. Can i use a switch case inside the Event???

Here is the sample code of multiple events:

if (button.SelectSingleNode("ButtonId").InnerText == "btnRefresh")
rButton.Click += new EventHandler<RibbonControlEventArgs>(btnRefresh_Click);
else if (button.SelectSingleNode("ButtonId").InnerText == "btnSaveToVGF")
rButton.Click += new EventHandler<RibbonControlEventArgs>(btnSaveToVGF_Click);
else if (button.SelectSingleNode("ButtonId").InnerText == "btnSubmit")
rButton.Click += new EventHandler<RibbonControlEventArgs>(btnSubmit_Click);

Now, I want to work on a single event and That event should handle all these events code. I mean all the code in btnRefresh_Click, btnSaveToVGF_Click, btnSubmit_Click into a single event button_click. so when i click this any button, this event should be handled and appropriate action should be taken using switch case.

Any help would be greatly appreciated.

Thanks & Regards,
K.S.Reddi Prasad.

Do something like this, private void my_button_Click (object sender, EventArgs e) { switch(((Button)Sender).InnerText) { case "btnRefresh": //do your stuff break; case "btnSaveToVGF": //do your stuff break; case "btnSubmit": //do your stuff break; } } Whats the problem!!

There are alternatives. You could use a collection such as a Dictionary to relate a Button object to other relevant data. You could use the Tag property to reference an object with other relevant data. Either one of those two could eliminate the need for a switch. A more object-oriented solution would be to derive a class from Button.

I think you must have altered this since I first answered it as the timestamp has changed and it's now clearer what you want to do. First of all, in the VS Properties Box you'll need to change the Click handlers of all 3 buttons so that they now point to button_Click or whatever you're going to call it. The code for that button's Click handler will then be: private void button_Click (object sender, EventArgs e) { Button btn = (Button)sender; switch(btn.Name) { case "btnRefresh": btnRefresh_Click(btn, e); break; case "btnSaveToVGF": btnSaveToVGF_Click(btn, e); break; case "btnSubmit" btnSubmit_Click(btn, e); break; } // anything else you want to do } If you're going to remove the existing handlers completely, then just replace the calls to those methods with their actual code.
