Set ALL fields to be ReadOnly that is on a web page

Question

User-1547820999 posted

Hello,

I am looking to change the ReadOnly to all the fields on my web page.  The text fields are named "resp_txt_xxxxx" where xxxxx is a number to make them unique.

I want to not have to code ALL of these fields (there are over 200 fields).

If anyone has done this, I would be greatly appreciative if you share.

Thanks!

You can try something like below...

Private Sub GetTextboxes()

Dim textBoxString As String

textBoxString = "System.Web.UI.WebControls.TextBox"

For Each control1 In Page.Controls

If control1.Controls.Count > 0 Then

For Each control2 In control1.Controls

If control2.GetType.ToString = textBoxString Then

Dim currentTextBox As New TextBox()

currentTextBox = CType(control2, TextBox)

currentTextBox.Text = "New Text"

currentTextBox.BackColor = System.Drawing.Color.Yellow

End If

Next

End If

Next

End Sub

This sub loops through the Web page's control collection. This collection consists of all controls on the page. An inner loop checks each of those controls for any child controls. When the code finds a "TextBox" control, it stores that control in the variable named "currentTextBox."

You should be able to either loop through all of the available Controls within your Page / Form and set the ReadOnly property to "False" as seen below : 

'Loop through each Control within your Page'
For Each control As Control In Controls
            'Check if it is a TextBox'
            If TypeOf control Is TextBox Then
                'If so - cast it properly'
                Dim yourTextBox As TextBox = DirectCast(control, TextBox)

                'Set it to ReadOnly'
                yourTextBox.ReadOnly = True
            End If
Next

If you wanted to have the values not be editable at all, you might consider using the Disabled property instead : 

yourTextBox.Disabled = True

which could also simply be applied to the entire form itself : 

Form.Disabled = True
