Default Using the IDs of dynamically created textboxes

Hi everybody,
My Page consists of a no. of textboxes created dynamicaly using the placeholder control.

  dim i as integer=1

  dim tb1 as textbox=new textbox()
  pl.add(tb1) 'Here pl is the placeholder control

Here I have given the ID of the textbox as tb1 but when I try to use it, like for eg.


I get the error : tb1 not declared.
Please advise me on how to use the ID.
Using the placeholder is mandatory and cannot be changed.
I am using VBScript for my coding

dim myTxtBox as textbox = myplaceHolder.FindControl("tb1")
dim myTxtBox2 as textbox = myplaceHolder.FindControl("tb2")

Try that. You must do that for all unless you loop through the placeholder.

Why don't you try it out?? ;)

Yes, that would work. FindControl expects the name of the control as a string, so combining the fixed "tb" with the number should work.

However, there are a few issues with the current code. First of all, you probably need to cast the control returned by FindControl to a real text box:
Dim i As Integer
Dim myTxtBox As TextBox 

For i = 1 To 5 'suppose i have 5 textboxes "tb1", "tb2"..."tb5"
  myTxtBox = CType(myplaceHolder.FindControl("tb" & i.ToString()), TextBox)
Second, you can't Response.Write the TextBox to get its text; you'll need to explicitly use its text property:
