How to add Clientside validation?

[speddi]

Hi,How do I check if the FormPanel is valid from the code behind? I noticed we can add listeners but I want to show an error message when the page is invalid and if it is valid, want to call a directevent. Can this be possible?


Or if I can check whether the panel is valid or not in the direct event, I can show a message bx and return.


Thank you

Hi,

On server side you you have to check each control manually (there is no validation logic on the server side) or use ASP.NET validators


You can check on client side and pass it to the server side as extra parameter of the DirectEvent

<ext:Parameter Name="valid" Value="#{FormPanel1}.isValid()" Mode="Raw" />

To show message box please use X.Msg class
