Hi:

I would like to be able force validation to fire from my asp .net page.
Basically, I catch the onChange() in a total amount field.
From that point, I'd like to force the ALL individual amount fields' validators to fire.
The individual amounts are contained in a custom user (ascx) control that's embedded in a repeater control.



I know how force validation on a single validator, I'd like to figure out to force it to fire on all the validators
embedded in the repeater control.



My asp .net page looks more or less like this:


===============================================================
This is what my asp:repeater control looks like:
===============================================================
<div id="div1">
    <asp:Repeater ID="Repeater1" runat="server"  >
        <HeaderTemplate>
            <table border="1" width="800px">
                <tr>
                    <td>
                        <strong> Repeater Header</strong>
                    </td>
                </tr>
        </HeaderTemplate>

        <ItemTemplate>
            <tr>
                <td class="indent vmid">
                    <uc1:CustomUserControl ID="CustomUserControl1" runat="server"                
                        Index ='<%# DataBinder.Eval(Container, "ItemIndex") %>'
                        FullName='<%# DataBinder.Eval(Container.DataItem, "FullName") %>'
                    />
                </td>
            </tr>
        </ItemTemplate>
   
        <FooterTemplate>
            </table>
        </FooterTemplate>
    </asp:Repeater>
</div>


===============================================================
This is what a snippet of my custom user control looks like (ascx)
===============================================================

<asp:Label ID="lTravelerTourCenterID" Width="10" runat="server" Visible="false"/>
<asp:Label ID="lFullName" Width="170" runat="server" />
<asp:TextBox ID="tAmount" Width="170" runat="server" />

<asp:RegularExpressionValidator ControlToValidate="tAmount"                         
      ValidationExpression="^[0-9]+(,[0-9]{3})*(\.[0-9]{0,2})*"
    ErrorMessage="Enter a valid amount" runat="server" ID="reValidator" Display="Dynamic" CssClass="error small" />

<asp:CustomValidator ID="cvtIndividualAmountPaxPayment" runat="server" ControlToValidate="tAmount"
      ClientValidationFunction="validatePaxPayments"
    ForeColor=" " CssClass="error small" ErrorMessage="Total pax payments exceed GL's account." Display="Dynamic"/>

<asp:CustomValidator ID="cvtIndividualAmountMinDeposit" runat="server" ControlToValidate="tAmount"  
      ClientValidationFunction="validatePaxMinDeposit" OnServerValidate="OnValidateMinPaxPayment"
    ForeColor=" " CssClass="error small" ErrorMessage="Payment cannot be less than minimal deposit." Display="Dynamic"/>

<asp:CustomValidator ID="cvtIndividualAmount" runat="server" ControlToValidate="tAmount"
      ClientValidationFunction="validateIndividualAmount" OnServerValidate="OnValidateIndividualAmount"
    ForeColor=" " CssClass="error small" ErrorMessage="Enter a valid payment amount" Display="Dynamic"/>

<div class="rowPayment smaller mrgl30" id="PaymentInfoType" runat="server" visible="false">
     <div class="columnA" id="divCheck" runat="server" >
         <exp:Check ID="checkPayment" runat="server" />
     </div>
</div>

Hi,

Please assign the validationGroup to controls and CustomValidators, lets suppose 2 textboxes and their CustomValidators have the ValidationGroup "ABC" and the button is also have the same validationGroup "ABC" then whenever button will submit it will verify all the validators who have group "ABC".

for reference please read the following article:
