ASP.NET - Multiple ValidationSummary

Question

Hello,

Scenario: I am trying to insert a team (composed by multiple persons) on a single page. I have a web user control to insert each person, and when a team has multiple persons several Web User Controls are displayed at the same time.

Each user has a ValidationSummary and several validators (All grouped to the same validation group, example person1 web user control has the validation group on de Validation summary and on each validator set to "valGroup_Person1").

The problem is when validation occurs all errors are grouped and displayed in all web user controls making each web user control display a very long error list. The expected was individual error lists.

Is there a way to get ValidationSummary to perform this way?

Thanks

If you are using asp.net 2.0 then you must use validation group this will work.

See the below example 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 have to disambiguate the validation groups from each other by giving them separate names on each of the controls. For example, in the user control's page-init:

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 validation group)

If you are doing server-side validation, you should call validation for just the group, e.g.

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