Hi,

By following way you call script funtion at clientside.

private void Button1_Click(object sender, System.EventArgs e)
{
string javaScript =
"";

RegisterStartupScript("Button1_ClickScript", javaScript);
}

Thanks.

Hi,

You used the imageButton, imageButton has ImageClickEventHandler.

for (int i = 0; i < 4; i++)
            {
                ImageButton btn1 = new ImageButton();
                btn1.Click += new ImageClickEventHandler(get);
                //Button btn = new Button();
                btn1.ID = "btn" + i;
                btn1.Height = 20;
                btn1.Width = 50;

                //btn.OnClientClick = "get()";
                Panel1.Controls.Add(btn1);
            }

        }
        public void get(object sender, ImageClickEventArgs e)
        {
            MessageBox.Show("hi");
        }
Thanks.

Hi,
Please try this.

protected void Page_Load(object sender, EventArgs e)
        {

            for (int i = 0; i < 4; i++)
            {
                Button btn = new Button();
                btn.Text = "Button " + i;
                btn.Height = 20;
                btn.Width = 50;

                btn.OnClientClick = "get()";
                Panel1.Controls.Add(btn);
            }
        }

Hope this will help you.

Thanks.
