To create a textbox at runtime you set it up in your Page_Init like this:
Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init
' Create dynamic controls here.
TextBox1 = New TextBox()
TextBox1.ID = "TextBox1"
TextBox1.Style("Position") = "Absolute"
TextBox1.Style("Top") = "25px"
TextBox1.Style("Left") = "100px"
Form1.Controls.Add(TextBox1)
TextBox2 = New TextBox()
TextBox2.ID = "TextBox2"
TextBox2.Style("Position") = "Absolute"
TextBox2.Style("Top") = "60px"
TextBox2.Style("Left") = "100px"
Form1.Controls.Add(TextBox2)
End Sub
Creating dynamic controls in ASP.Net can be a little tricky. The reason is any control created after the Page_Init will not be stored in the View State. This means for controls created after the Page_Init, on the page post back the data entered into the control will be lost. Furthermore events will not be fire for the those controls.
