[radhakrishnan]

Hello,

I Have a webform with one textbox and submit button
The TextBox is of the type Password(i.e
TextBox1.TextMode=TextMode.Password)

OnPageLoad of that form the following code is written
TextBox1.Text="Test"

After execution the the textbox value suppose to display ****
for "Test"(value of the TextBox1).But Textbox display is blank(but in the
debug textbox1.text="Test" only in the display it is blank).

How to do it in Asp.net?

Password TextBoxes do not render their value down to the client.
Imagine for a moment if they did: if the user left their machine, a
malicious coworker could do a View/Source and see that value in the
TextBox, thereby learning the person's password. Even if the user
closed down their browser, a knowledgeable person could look in the
browser's cache, and get at their password.

For this reason, ASP.NET's Password TextBox will not emit a value
attribute if the TextMode is Password.

Now, if you *had* to override this you could do one of the following:

(1) Create a custom control that derives from the TextBox class and
overrides its AddAttributesToRender() method.
(2) Emit the actual HTML markup you want, perhaps using a Literal
control to precisely place where the TextBox should be. To read the
incoming value you'll have to read from Request.Form["Name of TextBox"]
