Hi everyone,
I want to add any control dynamically in panel or layout.Can any one told me in which panel or layout i can add control dynamically.
I tried to add checkbox in panel(RadXmlHttpPanel also).

protected void Page_Load(object sender, EventArgs e)

{

}

protected void RadMenu1_ItemClick(object sender, Telerik.Web.UI.RadMenuEventArgs e)

{

lblContent.Text = "u clicked " + e.Item.Text;

}

protected void RadToolBar1_ButtonClick(object sender, Telerik.Web.UI.RadToolBarEventArgs e)

{

lblContent.Text = "u clicked " + e.Item.Text;

}

protected void RadTabStrip1_TabClick(object sender, Telerik.Web.UI.RadTabStripEventArgs e)

{

lblContent.Text = "u clicked " + e.Tab.Text;

}

protected void RadButton_addControl_Click(object sender, EventArgs e)

{

int i;

for (i = 0; i < 4; i++)

{

CheckBox ch = new CheckBox();

ch.ID = "ch" + i.ToString();

this.form1.Controls.Add(ch);

}

in xml
