ASP.NET - Multiple Validation

Script . I am trying to embed a team (consisting of several people) in one page. I have a web user control to insert each person and when a team has multiple people, multiple web user controls are displayed at the same time.

Each user has a ValidationSummary and multiple validators (all grouped into the same validation group, for example the user control person1 example1 has a validation group in the validation summary and on each validator set to "valGroup_Person1").

The problem is that when checked, all errors are grouped and displayed in all web user controls, and each custom control displays a very long list of errors. Separate error lists were expected.

Is there a way to force ValidationSummary to execute this path?

If you are using asp.net 2.0 you must use a review group, this will work.

See example below, it will work







        
        

    

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" 
    ControlToValidate="TextBox1" ErrorMessage="RequiredFieldValidator" 
    ValidationGroup="1">1</asp:RequiredFieldValidator>
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" 
    ControlToValidate="TextBox2" ErrorMessage="RequiredFieldValidator2" 
    ValidationGroup="2">2</asp:RequiredFieldValidator>
<asp:ValidationSummary ID="ValidationSummary1" runat="server" 
    ValidationGroup="1" />
<asp:ValidationSummary ID="ValidationSummary2" runat="server" 
    ValidationGroup="2" />
<asp:Button ID="Button1" runat="server" Text="Button" ValidationGroup="1" />
<asp:Button ID="Button2" runat="server" Text="Button" ValidationGroup="2" />

You must disambiguate the validation groups from each other by giving them separate names on each of the controls. For example, on the user management page:

Private Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
    Dim uniqueGroupName = Guid.NewGuid.ToString
    valSummary.ValidationGroup = uniqueGroupName
    txtFirstName.ValidationGroup = uniqueGroupName
    txtLastName.ValidationGroup = uniqueGroupName
    btnFind.ValidationGroup = uniqueGroupName
End Sub

(for each control in the group, programmatically give it a check group)



If you are doing server side validation, you should invoke group only validation, eg.

Page.Validate(valSummary.ValidationGroup)
If Not Page.IsValid then Exit Sub
