Hi,
i have a form that when the user finish,he clicks save and then a message is shown to say"data is saved".
how can i add a button that says to close the window click here after the save button is clicked that comes with the message?

You can add the html input tag with the message and set the text of the literal control

Eg:
litMsg.Text = "data is saved, Now you can close the window " + "<input type='button' value='close' onclick='javascript:window.close();' >"

Prashant.K.M,
thanks for your reply ,but when i wrote the suggested solution as following in my code behind page:
 Label1.Text = "Your Data Is Saved" + "<input type='button' value='close' onclick='javascript:window.close();' >"


it show me "data is saved"only without the button.is there something wrong with the code or should i write it in another way?

i had this working after debugging the project,but how to make the save button hidden or not shown when the message appears?

You can directly set the "btnSubmit.visible=false;"
