Page.Controls(0 ).FindControl(" tbxCompetitor01 Product")

[sck10]

Hello,

I am looping through each control using the following to find a particular
control (strFindCtl = "tbxCompeti tor" & strForLoop1 & "Product").

For ctrRow = 1 To 3
strForLoop1 = "0" & ctrRow
strFindCtl = "tbxCompeti tor" & strForLoop1 & "Product"
For Each ctlMaster As Control In Page.Controls ' Page
If TypeOf ctlMaster Is MasterPage Then '
MasterPage
For Each ctlForm As Control In ctlMaster.Contr ols
If TypeOf ctlForm Is HtmlForm Then '
HtmlForm
For Each ctlContent As Control In ctlForm.Control s
If TypeOf ctlContent Is ContentPlaceHol der Then
'ContentPlaceHo lder
For Each ctlChild As Control In ctlContent.Cont rols

If TypeOf ctlChild Is TextBox Then
If ctlChild.ID = strFindCtl Then strSubmitter &=
CType(ctlChild, TextBox).Text & ", "
End If

Next
End If
Next
End If
Next
End If
Next
Next


Based on the article
(http://dotnetjunkies.com/WebLog/jpal...01/23919.aspx), I
am trying to follow the format for the following in order to reduce my code:
(MyUserControl) Page.Controls[0].FindControl(†�ucMyUserContro l�);

However, when I use the following:

Dim ctlSteven As Control =
Page.Controls(0 ).FindControl(" tbxCompetitor01 Product")
Response.Write( ctlSteven.ID)

I get the error:
I get the error: System.NullRefe renceException: Object reference not set to
an instance of an object.

Any help with this would be appreciated.

Hi sck10:

You have to be aware of 'naming containers' when using FindControl.
You'll need to invoke FindControl on the ContentPlaceHol der instance.

For an example of what I mean, see my article:

Hi Scott,

For my loop, I referenced the contentplacehol der on the master page as you
suggested (and it works!). One thing I ran into is that I was unable to
figure out how to reference the the "Content" control (id="Content1") on the
content page or if I even need too. Thanks again for your help...

This is on the master page:
<asp:ContentPla ceHolder ID="cphMainCont ent"
Runat="server"> </asp:ContentPlac eHolder>

Is on the content page:
<asp:Content ID="Content1" ContentPlaceHol derID="cphMainC ontent"
Runat="server">

This works...
For ctrRow = 1 To 3
strForLoop1 = "0" & ctrRow
strFindCtl = "tbxCompeti tor" & strForLoop1 & "Product"
ctlFind = Master.FindCont rol("cphMainCon tent").FindCont rol(strFindCtl)
strFrmObj = CType(ctlFind, TextBox).Text & "<br>"
Response.Write( strFindCtl & " = " & strFrmObj)
Next
