尝试一下:

Try this:

BtnServices = new Button();
BtnServices.ID = "BtnServices";
BtnServices.Text = "Click Me";
BtnServices.Click += new System.EventHandler(BtnServices_Click);

void BtnServices_Click(object sender, EventArgs e)

仅分配一个代表，该事件就不会触发.您必须调用委托.

您必须将此按钮呈现到aspx页面，必须处理视图状态，然后当用户单击按钮时，事件将触发.

如果您不渲染按钮，用户将如何单击它.
如果您不渲染按钮，并且想要该功能，则可以像这样调用该函数.

Hi,

Just by assigning a delegate, the event will not fire. You must invoke the delegate.

you must render this button to the aspx page, you must handle the view state, then when user clicks on the button, then the event will fire.

if you are not rendering the button, how user will click on it..??

if you are not rendering the button and if you want that functinality, just call that function like this.

BtnServices_Click(BtnServices, new EventArgs();

祝您编码愉快.

Happy Coding.
