Hello Devang,

From Q2 2012, you can set RequireCompleteText="true" for the RadMaskedTextBox, and and it will require full text to be entered in order to pass value to the RequiredFieldValidator different than empty string.

Hi Vasil,

RequireCompleteText="true" also validates empty values. I do not want to validate if user does not put any thing in it. Is there any property available for it??

Look at attached image. 

Here is my skin for ZipExtension text Box:

<telerik:RadMaskedTextBox SkinID="sknZipExt" runat="server" Width="50px" MaxLength="4" Mask="####" SelectionOnFocus="SelectAll" RequireCompleteText="true"  />

Is there other way to validate this is except using regular expression validator and validate entire text.

Thanks,

Hi Tarang,

Well it is not supported out of the box.
But you could override some methods in order to make it work. Here is the original code, and you can add an additional checks as per your requirements:

    Telerik.Web.UI.RadMaskedTextBox.prototype._constructValidationText= function (value)
{
    if (this.get_value() && !(this._requireCompleteText && this.get_valueWithPromptAndLiterals() != this.get_valueWithLiterals())) //add additional checks here
    {
        return this.get_valueWithLiterals();
    }
    else
    {
        return "";
    }
}

Telerik.Web.UI.RadMaskedTextBox.prototype.raise_valueChanged= function ()
{
    this._triggerDomEvent("change", this._textBoxElement);
    this._holdsValidValue = true;
    if (this._requireCompleteText)
    {
        if (this.get_valueWithPromptAndLiterals() != this.get_valueWithLiterals())
        {
            //add additional checks here
            return this._invalidate();
        }
    }
    var tempOldValue = this._textBoxElement._oldValue;
    this._textBoxElement._oldValue = this._textBoxElement.value;
    this._OnValueChange(null, tempOldValue, this._textBoxElement.value);

}

Also you may want to override the function ValidationText of server side RadMaskedTextBox class. Its current code is:

public override string ValidationText
 {
     get
     {
         if (String.IsNullOrEmpty(Text) ||
             (this.RequireCompleteText && (TextWithPromptAndLiterals.Length != TextWithLiterals.Length)))
         {
             return String.Empty;
         }
         return TextWithLiterals;
     }
 }
