how to add buttons in content place holder at runtime in asp.net?

Question

In my form i have added one content place holder and also added a button within th e content place holder manually.But now i want to add a button in the same content place holder at runtime. I tried the following code, but the button is not showing in the browser... I don't know what is the problem here...

My Code...

ContentPlaceHolder content = (ContentPlaceHolder)this.Master.FindControl("maincontent");
Button newButton = new System.Web.UI.WebControls.Button();
newButton.ID = "NextButton";
newButton.Text = "Next";
newButton.Visible = true;
content.Controls.Add(newButton);

Are you using Visual Studio? Put a Watch on `content` and see if: a) you've actually found it; b) it contains newButton. — Yehuda Shapira, Sep 21 '12 at 08:53

You've lost the size and location of your button.

Drop the

ContentPlaceHolder content = (ContentPlaceHolder)this.Master.FindControl("maincontent");

Change your code to

Button newButton = new System.Web.UI.WebControls.Button();
newButton.ID = "NextButton";
newButton.Text = "Next";
newButton.Visible = true;
maincontent.Controls.Add(newButton);

Assuming that 'maincontent' is the ID you've given your placeholder, or course.
