clearing all text boxes on a web form
Howdy, I picked up the following code a while back but have only now had the time to try it.
what I would like to do is clear the content of all the text boxes on a web form.
here is the code:
Private Sub ReadControls()
Dim ctl As Control
Dim intIndex As Integer
' First find the Form object
For Each ctl In Page.Controls
If ctl.GetType Is GetType(Web.UI.HtmlControls.HtmlForm) Then
intIndex = Page.Controls.IndexOf(ctl)
Exit For
End If
Next
' Loop through all controls within Form Control
' which is at Postion 1 in the Controls Collection
For Each ctl In Page.Controls.Item(intIndex).Controls
If ctl.GetType Is GetType(TextBox) Then
Response.Write(CType(ctl, TextBox).ID & " = ")
Response.Write(CType(ctl, TextBox).Text & "")
End If
Next
everything seemed to be going fine, it correctly detects the textboxes.
but then it seems to simply write the values to the screen...
Response.Write(CType(ctl, TextBox).ID & " = ")
Response.Write(CType(ctl, TextBox).Text & "")
I must be missing something simple.
I tried to access the <code>ctl.TEXT<\code>
attribite of the control, but it is not available...I'm guessing that it is because it is declared as a generic control.can anyone help me out?I'd say there's a few folk out there who'd be keen on putting this one to bed.
it all seemed so easy in vb6.
Many thanks,
yogi

Can someone explain this code for me
What I'm wondering is what does the first loop do? Can I skip it?
thanks.
Dim ctl As Control
Dim intIndex As Integer
' First find the Form object
For Each ctl In Page.Controls
If ctl.GetType Is GetType(Web.UI.HtmlControls.HtmlForm) Then
intIndex = Page.Controls.IndexOf(ctl)
Exit For
End If
Next
' Loop through all controls within Form Control
' which is at Postion 1 in the Controls Collection
For Each ctl In Page.Controls.Item(intIndex).Controls
If ctl.GetType Is GetType(TextBox) Then
Dim txtbx As TextBox
txtbx = CType(ctl, TextBox)
txtbx.Text = ""
End If
If ctl.GetType Is GetType(ListBox) Then
Dim txtbx As ListBox
txtbx = CType(ctl, ListBox)
txtbx.SelectedIndex = 0
End If
Next

The first loop tries to find the Form on the page. It would be more efficient to retain the reference to the form control instead of just keeping its index, though.
The problem with this code is that it won't find all textboxes but only the textboxes that are directly under the form.
You would need to make a function that recursively explores the Control tree to be really complete.

What other textboxes would there be? When you say only in the form. Can you give an example of when it would not be in the form. Sorry so brief, but I'm out the door (Mom's Birthday).
thanks.

TextBoxes in a NamingContainer inside the form. Controls form a tree, and that can be deep.
Example: textboxes in a repeater.

Most of what I'm doing is database lookup, insert.... In my scenario I'd bring back data into a single form and not repeater controls. What I've posted works great. I've included textboxes, dropdownlists, radiobuttonlists and such.
Thanks for the quick replies. I really enjoy working with asp.net comming from cold fusion.
Again Thanks :)

Sure, it works in most cases.
I was just mentioning it so that other people who have the same problem but have nested stuff can figure it out and make it work too.
