In my case, the problem was having two

tags.

I have a TextBox in my main page. If the user enters a value in this TextBox, a Script goes to another page and searches that value while user continues to write it. Normally I created this "another" page by clicking Website, Add New Item. So Visual Studio created a new page for me. As usual there was

tag in this new page, too. So I deleted this tags and the problem was solved.

Below are my codes:

(PS: I use MasterPage. But the below code is only needed in my main page)

    Dim scriptText As String
    scriptText = ""
    scriptText += "function serinogoster(str) {" + Chr(10)
    scriptText += "var xhttp;" + Chr(10)
    scriptText += "if (str == '') {" + Chr(10)
    scriptText += "document.getElementById('ctl00_ContentPlaceHolder1_Label19').innerHTML = '';" + Chr(10)
    scriptText += "return;" + Chr(10)
    scriptText += "}" + Chr(10)
    scriptText += "xhttp = new XMLHttpRequest();" + Chr(10)
    scriptText += "xhttp.onreadystatechange = function() {" + Chr(10)
    scriptText += "if (this.readyState == 4 && this.status == 200) {" + Chr(10)
    scriptText += "document.getElementById('ctl00_ContentPlaceHolder1_Label19').innerHTML = this.responseText;" + Chr(10)
    scriptText += "}" + Chr(10)
    scriptText += "};" + Chr(10)
    scriptText += "xhttp.open('GET', 'serinover.aspx?serino='+str, true);" + Chr(10)
    scriptText += "xhttp.send();" + Chr(10)
    scriptText += "}" + Chr(10)
    Me.ClientScript.RegisterClientScriptBlock(Me.GetType(), "OnKeyUpScript", scriptText, True)
    TextBox6.Attributes.Add("onkeyup", "serinogoster(this.value);")

In the above code serinover.aspx is the second page which should not have

tag.
