you can try setting the ClientID of your controls to "Static" and that should fix the ID of the controls to whatever you define when you are creating them dynamically.

Solution 1

The ClientID property of your buttons will contain the id they will have on the client side, once they have been added to the page's controls collection.

If you wish to get the button's ID from within the Button's click event handler, you can cast the first parameter (sender) to the Button and get it's ID like this:

C#

Button btn = sender as Button;
string ID = btn.ID;

Solution 2

You can take the help of Sender object.

Write the code inside the button_Click method.

C#

private void button1_Click(object sender, EventArgs e)
        {
            Button b = sender as Button;
            label1.Text = b.Name;
        }

Fun coding.....
