TextboxWatermarkExtender and Textbox with TextMode = Password

I managed to do this by setting the watermark stylesheet to overlay an image in the textbox.

You simply take a snapshot of how you want the watermarked textbox to look, save that, then set the watermark css of that textbox to a style that displays the image and aligns the text to the right (because otherwise it will still be visible)

It's very easy and works flawlessly.

The Textbox:

<asp:TextBox ID="Password" runat="server" CssClass="txtbox_login" Width="120px" TextMode="Password">

The Watermark (Set the WatermarkText property to anything you want, but just one character):

<ajax:TextBoxWatermarkExtender ID="txtWMark2" runat="server" WatermarkCssClass="watermarked_psw"TargetControlID="Password" WatermarkText="*" />

The StyleSheet (You MUST align the text to the right, otherwise it will still display over the image):

.watermarked_psw

{

color: White;

font-family: Tahoma;

font-size: 11px;

border: solid 1px #a9a9a9;

text-indent:2px;

vertical-align:middle;

text-align:right;

background-image:url(../images/psw_wMark.png);

background-repeat:no-repeat;

}

It works !
