C#: How to remove delegation of a ToolBarButton's click event...

[Saravanan Krishnan]

Hi, everybody...

I'm developing a c# windows application where my app has more than 2 forms in it. i've placed some toolbarbuttons on it. I've associated toolbarbuttons click events to it. Now what i need is to remove the associated methods of those tbbtns on some condition. I'm able to add delegates to those btns at any moment but i have no idea how to remove those delegations...

Any help is appriciable...

Thanks in advance.

Hello Saravanan,

You can just remove delegate.

Following is a sample that describes how to remove an event delegate.

//delegate is added for button click event
this.button2.Click += new System.EventHandler(this.button2_Click);

//delegate for button click event is removed
this.button2.Click -= new System.EventHandler(this.button2_Click);

hey bala,

i've did same thing to remove the button's association with the event handler method. that is

btn.click -= new eventhandler(my btn_click);

but when the other form is opened i execute the above mentioned line. but even then when the same button in the current form(newly opened) is clicked, the event handler method present in the previously opened form gets executed and then the newly opened forms method gets executed.

I Conform that "[btn.click -= new eventhandler(my btn_click);"] gets executed, but then also mybtn_click() method is called first. How is this possible after removing the delegation for that btn and method...

if u dont understand this reply u can ask for the code as well...
