[RESOLVED] Checkbox control on content page

[MechEng]

How can I access a checkbox control on a content page if I know the checkbox’s ID?

I have tried the code below, but using Me.Controls does not seam to generate a controls collection beyond the MasterPage… or I am way off target and have not figured it out yet.

Thanks for your help in advance.

            Dim ctr As Control
            Dim s as String
 
            For Each s In Str_ArrayList ‘these are the checkbox IDs

                For Each ctr In Me.Controls
                    If ctr.ID = s Then
                        CType(ctr, CheckBox).Checked = True
                    End If
                Next
            Next

As you have placed control inside the Content place holder try the

Me.ContentPlaceHolder.Controls method

That did the trick. Thanks for the tip.

            Dim contentPlaceHolder As ContentPlaceHolder
            contentPlaceHolder = CType(Page.Master.FindControl("ContentPlaceHolder1"), WebControls.ContentPlaceHolder)

            Dim ctr As Control
            For Each s In Str_ArrayList

                For Each ctr In contentPlaceHolder.Controls
                    If ctr.ID = s Then
                        CType(ctr, CheckBox).Checked = True
                    End If
                Next
            Next

Why not just reference it by its ID name in the codebehind, as that's going to be available to you for all the controls.

The control names are pulled from a database at runtime (when the page is loaded). If there was a way to directly reference the controls with a variable name, I would prefer to do that. A direct reference has to be more efficient than looping through all the controls (> 150 checkboxes alone) each time, although this event does not occur that often.
