Usercontrol not rendered in table

[Anon]

I am programmatically populating an asp.net table control with my usercontrol
(PictureBox.ascx) which is basically an assortment of an imagebutton, Label
and a Linkbutton. Now while debugging the application i can see that the
control is being initialized properly (by setting the imgurl and text values
from the db, both of these are Image and label properties of the page
respectively. i am using these properties to set the actual image and label
controls on the user control page in its page load event), but for some
reason the usercontrol does not show up in the table. Why?
For e.x. PictureBox.ascx
private void Page_Load(object sender, System.EventArgs e)
{
// Put user code to initialize the page here
lblCaption = this.TextCaption;
ibtnPicture = this.Picture;
}
