How do I clear a RadMaskedTextBox

[Derek]

Hi there,

I'm looking for a way to clear a RadMaskedTextBox on the client side.  Although the Clear() method is not listed in the documentation, it does work on the masked textbox.  See below:

function RemovePhone(which)
{
   var radInput = window["<%= phoneRadMaskedTextBox0.ClientID %>"];
   radInput.Clear();
}

However, i'm looking for a way to pass in the element id "which" and clear only that text box:

function RemovePhone(which)
{
   var radInput = document.getElementById("ctl00_ContentPlaceHolder2_phoneRadMaskedTextBox" + which);
   radInput.Clear(); // doesn't work
   radInput.text = ''; // doesn't work
   radInput.value = ''; // doesn't work
}

Hi Derek,

You need the masked text box client object in order to call its client-side functions. The client object can be obtained through the window["id"]. The second syntax will bring the DOM element to you, which is not supposed to have any client-side functions.

Hi, I am having a similar problem - only I need to clear RadMaskedTextBox on the server side.
I have a range of numerics defined, so that my mask is a 7 digit text (each letter can be 0-9), so that when the control loads for the first time it looks like this 0000000 (kind of a default value).
is there a way for me to reset it beck to this default in a generic way ?

thanx,
Revital

Hello Revital,

You can clear the MaskedTextBox value server-side by setting its Text to empty string (""). I have attached a sample which illustrates that.

Hi Konstantin ,
Thnak u for your reply, but I have already tried that and it doesn't work because , as I said before, I have the following mask defined : "<0..9><0..9><0..9><0..9><0..9><0..9><0..9>", which loads with the default Text of "0000000".
My question is if there's a way in which I can "clear" the Text value back to the default Text it loads with.

Thanks again,
Revital

Hi Revital,

Is there a reason why you can't just set the text to the default value ("0000000") when you want to "clear" the current masked input value?

Let us know if I'm missing something out.

I wanted to  use a generic way to clear all RadMaskedTextBox's to the initial Text value from design time.
In your solution I have to hard code the value for each instance of the control with no way of doing it generically...
