如何在Visual Studio C＃中禁用和启用按钮上的click事件

Question

I have a form with 10 buttons.

When I click any of the buttons, it should be disabled so that I can't click on it again, but it should be re- enabled again when I click on any other button.

I know there is a way to do it, disabling and enabling the control (button) but I don't want to use this method because I want to change the colour of the button when it is in use (when its clicked), and if the button gets disable it will get its original colour.

So I want to know if there is a way to do it. Thanks

Answer 1

Just use a variable

private bool isClicking = false;

public void SomeEvent()
{
   if (isClicking) return;
   try
   {
      isClicking = true;
      // do some codes
   }
   finally
   {
      isClicking = false;
   }
}

Though in truth, the usual course of events for this situation is you disable your button not color it

This is the code I'm using

bool btn1,btn2,btn3;

private void button1_Click(object sender, EventArgs e)
{
     AvtivateButtons(1,btn1);
}

private void ActivateButtons(int btn, bool btnState)
{

            switch (btn)
            {
                case 1:
                    button1.Click -= button1_Click;
                    btnEstate = false;
                    break;
                case 2:
                    button2.Click -= button2_Click;
                    btnEstate = false;
                    break;
                case 3:
                    button3.Click -= button3_Click;
                    btnEstate = false;
                    break;
            }

            if (!btn1)
            {
                button1.Click += button1_Click;
            }
            if (!btn2)
            {
                button2.Click += button2_Click;
            }
            if (!btn3)
            {
                button3.Click += button3_Click;
            }


            btnState = true;

}

You should put a javascript method to return true or false. When a javascript method returns false, the post back will be skipped.

<asp:Button ID="mybutton" OnClientClick="return JS_Method();" OnClick="PostBackMethod_Click" />

Answer 4

Finally I found a way to do it.

bool[] buttons = new bool[10];

private void button1_Click(object sender, EventArgs e)
{
     if (buttons[0])
     {
         // Code.....

         buttonToggle(0);

         // Here I change the color based on the estate of the correspondent bool variable
     }
}

private void buttonToggle(int btn)
{
    buttons[btn] = false;

    for(int i = 0; i<10; i++)
    {
        if (i != btn)
        {
            buttons[i] = true;
        }
    }
}

Thanks @TheGeneral for the idea
