                  button2.ID = ddr[2].ToString();
                button2.Style[" border-style"] = "solid";
                button2.Style["background-color"] = "#063a83";
                button2.Style[" border-width"] = "3px";
                button2.Style[" color"] = "White";
                button2.Style[" font-family"] = "Tahoma";
                button2.Style[" border-color"] = "Gray";
                button2.Style[" border-radius"] = "10px";
                button2.Style[" background-image"] = "url(../images/products/zoom2.png)";
                button2.Style[" background-repeat"] = "no-repeat";
                button2.Style[" padding"] = "10px";
                button2.Style["Cursor"] = "pointer";


               button2.Click += new System.EventHandler(detail_Click);

                Panelproduct.Controls.Add(button2);

Answer 2

Add a CssClass to you button like this:

Button button2 = new Button();

button2.Text = "buy";
button2.ID = ddr[2].ToString();
button2.CssClass = "btn"; //add a css class

button2.Click += new System.EventHandler(detail_Click);
Panelproduct.Controls.Add(button2);

Then in your css stylesheet add styles for that class, like so:

.btn{
    border-style: solid;
    background-color: #063a83;
    /*more styles*/
}

.btn:hover{
       background-color :#202020 ; 
       cursor:pointer;
    }
