Display invalid message in radtextbox ?

[guillaume monore]

Hello !

    I would like to know how to display an invalid message in a radtextbox when values are not what we expected.

i got a synergieTextbox that herites from a radtextbox and overload the load method:

 

 

 

protected override void OnLoad(System.EventArgs e)

{

 base.OnLoad(e);

 this.InvalidStyle.BackColor = Color.Yellow;

 this.ClientEvents.OnLoad = "fnOnUpdateValidators";

 this.ClientEvents.OnValueChanged = "fnOnUpdateValidators";

}

i got my textbox here :

 

 

 

<syn:SynergieTextBox  CausesValidation="true"  Width="300px"

 Text='<%# Eval("FirstName") %>' ID="txtFirstName" runat="server">



</syn:SynergieTextBox>

and the javascript here :

 

function     fnOnUpdateValidators(sender, eventArgs) {           if (typeof (Page_Validators) != "undefined") {               for (var i = 0; i < Page_Validators.length; i++) {                   var val = Page_Validators[i];                   var ctrl = document.getElementById(val.controltovalidate);                   if (ctrl != null && sender != null) {                       if (sender._clientID == ctrl.id) {                           if (!val.isvalid) {                         sender._invalid =     true;                         sender.updateCssClass();                             break;                     }                         else {                         sender._invalid =     false;                         sender.updateCssClass();                       }                   }               }           }       }   }

I would like to add text like sender.MyInvalidText = Val.ErrorMessage;

how to do something like that ?

hi friend!

can u specify the controls that u are using to contain your textbox?, maybe u have to tell everyone more to go on resolving this issue, please upload fully your source code if u dont mind.

kind regrads.

there is nothing else in the synergie control, only this overload to make every radtextbox having the same behavior

public class SynergieTextBox : Telerik.Web.UI.RadTextBox
    {
        protected override void OnLoad(System.EventArgs e)
        {
            base.OnLoad(e);
            this.InvalidStyle.BackColor = Color.Yellow;
            this.ClientEvents.OnLoad = "fnOnUpdateValidators";
            this.ClientEvents.OnValueChanged = "fnOnUpdateValidators";
        }
    }

Hi Guillaume,

Could you please let me know which exactly RadControl you are using in your application and which of them is the problematic one. Some more information on your scenario and the controls you are using could help us provide more to-the-point solution
