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 ?

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";

}
