Adding unique ValidationGroup names to forms - asp.net

Question

I have a problem when adding modules/controls to a webpage in a ASP.NET CMS which have form validation that it would validate all forms on the page, because the ValidationGroup has the same name. How to solve this with a function?

Answer 1

I came up with below solution:
A function that iterates through a certain placeholder to assign unique ValidationGroup names to each form.
Public Shared Sub SetValGroupControls(PageModule As Control, valGroupName As String)
For Each ctrl As Control In PageModule.Controls
If TypeOf ctrl Is RequiredFieldValidator Then
DirectCast(ctrl, RequiredFieldValidator).ValidationGroup = valGroupName
ElseIf TypeOf ctrl Is RegularExpressionValidator Then
DirectCast(ctrl, RegularExpressionValidator).ValidationGroup = valGroupName
ElseIf TypeOf ctrl Is CompareValidator Then
DirectCast(ctrl, CompareValidator).ValidationGroup = valGroupName
ElseIf TypeOf ctrl Is CustomValidator Then
DirectCast(ctrl, CustomValidator).ValidationGroup = valGroupName
ElseIf TypeOf ctrl Is RangeValidator Then
DirectCast(ctrl, RangeValidator).ValidationGroup = valGroupName
ElseIf TypeOf ctrl Is Button Then
DirectCast(ctrl, Button).ValidationGroup = valGroupName
End If
If ctrl.Controls.Count > 0 Then
SetValGroupControls(ctrl, valGroupName)
End If
Next
End Sub
Where PageModule represents the placeholder where the validation controls are contained (to avoid iterating through all controls on the page) and the ValGroupName represents the unique string which will be assigned as name.
Assuming my validation controls are contained in a placeholder that is called 'plhMyForm' you can call the function like this:
Dim nGuid = String.format("{0}-validation", Guid.NewGuid())
SetValGroupControls(plhMyForm, nGuid)
Above will create a unique string like:
24ad5ae3-fead-4a6f-98f3-dffcd2e815ba-validation
Of course you can use your own unique string generation.
Now you can leave your ValidationGroup name empty and the function assigns one for you. This way every form on the same page that requires validation will individually validate itself.
