Method 1

PasswordChar property is under this namespace, System.Windows.Forms. It is not available for asp .net web applications.

You could try JavaScript to change it into other characters such as “*” or “@”.

You can see the following example to do so:

<script type="text/javascript">
        function onTextChange(obj)
        {
            document.getElementById('hdnActualTextValue').value = obj.value;
            obj.value = '';
            for(int i=0; i<obj.value.length;i++)
            {
                obj.value +='*';//OR ANY OTHER CHARACTER OF YOUR CHOICE
            }
        }
        </script>

        <asp:TextBox ID="txtValue" runat="server" onblur="javascript:onTextChange(this);"
            onkeyup="javascript:onTextChange(this);" onkeypress="javascript:onTextChange(this);"></asp:TextBox>
        <asp:HiddenField ID="hdnActualTextValue" runat="server" />

OR maybe you could use input in HTML.

<label>PW: <input type="password"></label>

Method 2

I think if you are using the Web Forms then in that the Password Characters are fixed. You can not change unless you use Javascript to change some behavior at run time

When we use WebForms in that PasswordCharacters are set by default.

Method 3

Simply use TextMode property in asp

<asp:TextBox ID="txtValue" runat="server" TextMode ="Password"> </asp:TextBox>
