How can i dynamically create a textBox and a Masked Edit extender inside a Panel. My code is something like this: In the ASPX page:

In the Aspx.cs page Private DataView Function1() { Dataview dv =new dataview(); return dv; }

Private void ShowProducts_OntemDataBound(object sender, RepeaterEventItem e) { //Consider For the First Iteration of the Repeater I am Creating a Simple Text Box Dynamically Textbox txt = new textbox(); txt.Text = "8888888888"; txt.Id = "TextBox1";

//Consider For the Second Iteration of the Repeater I am Creating another TextBox and a Textbox txt1 = new textBox(); txt1.text="2223334444"; txt1.Id = "TextBox2";

MaskedEditExtender mskEdit = (MaskedEditExtender)e.Item.FindControl("MskEdit"); mskEdit.TargetControlId = txt1.Id;

Panel panel1 = (Panel)e.item.Findcontrol("Panel1"); panel1.Controls.Add(txt1); }

When running the above code it is giving me "Null Reference Exception for MaskedEditExtender".Please suggest me some way for this.
