Question

hi im have a very common problem but unable to find any answer
i have a div and there are validator controls in it. I have used br tag in ErrorMessage Text to show show each message in new line. My code is below

    <asp:RequiredFieldValidator ID="RequiredFieldValidator1" CssClass="lblMessageError"
        runat="server"  ErrorMessage="<br> User name field cannot be empty" ControlToValidate="txtUserName" SetFocusOnError="True"></asp:RequiredFieldValidator> 
    <asp:CustomValidator ID="CustomValidator1" runat="server" ClientValidationFunction="ClientValidate" ControlToValidate="txtPassword" CssClass="lblMessageError" ErrorMessage="<br />The password must be more than 6 characters."></asp:CustomValidator>  
    <asp:CompareValidator ID="CompareValidator1" runat="server" CssClass="lblMessageError" ControlToCompare="txtPassword" controlToValidate="txtRePassword" ErrorMessage="<br /> Password dont match with repassword"></asp:CompareValidator>  
</div>

when there is no error found then it show line breaks. all i want is when there is not error found line breaks are ommitted.

1) when all validators are hidden

‘<%–line Break because no error found–%>
‘<%–line Break because no error found–%>

‘ <%–line Breakbecause no error found—%>

2) when one validator is visible and other and hidden

User name field cannot be empty
‘ <%–line Break because no error found–%>
‘ <%–line Breakbecause no error found—%>

‘<%– ally my controls here–%>

and i also dont want to show all my errors in same line
any suggestions??

Add the Display="Dynamic" attribute to your validator, eg:

 <asp:RequiredFieldValidator ID="RequiredFieldValidator1" CssClass="lblMessageError"
    runat="server"  Display="Dynamic" ErrorMessage="<br> User name field cannot be empty" ControlToValidate="txtUserName" SetFocusOnError="True"></asp:RequiredFieldValidator>
