Is there anyway of retrieving value's from Script variables into the code behind window in ASP.net.

My problem is thus,

I have a message box that I use to ask a question, (that was kindly provided by the Rohit Kureki Guru) , now I want to use the value that was obtained by that message box, and use the value to Dynamically create control's on the Web form?
I would like to do this in the code behind module!!

Hi cykophysh,
Try the code below
System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("<script language=javascript>") ;
sb.Append("var x = prompt('Enter a number','');") ;
sb.Append(" if (x)");
sb.Append("{document.forms(0).TextBox2.value=x;");
sb.Append("}");
sb.Append("</script>");
if (!(IsStartupScriptRegistered("HighTher")))
RegisterStartupScript("HighTher", sb.ToString());
U won't b able to c the code. So View->Source
I feel therez a prob with this code snippet I wasn't able to use the textbox2's val in the page_load fn. But, the val was shown there in the TextBox. So, if u or anybody else has a better way then pls let me also know it.

And BTW thanx for calling me a guru (hehehehe)

hope this helps

But................

I want to transfer the value of the msgbox,
I want to use Vbscript to build the msgbox, for the purpose that I want a yes/No msgbox, I can't seem to find that in Javascript.

So I need to figure out how to get the the value of the answer that was returned, from the messagebox, then I need to Load up a place holder control with some server control's
i.e Label, Textbox, and Validation control,

I'm sorry if I seem to be asking the same question's all the time, but I'm just finding it difficult to comprehend this .NET stuff!!

Try to use the confirm("Do you really want to do that ?") function provided by Javascript! This may help you to get a yes or or no value by the user. You can use the code as following:


function VerifyDelete(message)
{
if(confirm(message))
alert("You pressed yes");
else
alert("You pressed no");
}

Okay, this is my Problem that I have, I have had a ton of replies but none seem to fit my solution!!

What I want to do is take the value form this sub
<script language="vbScript">
sub TestThis()
dim intResult
if not ispostback then

intResult = MsgBox("Is this a Divisional Op Order?", vbYesNo, " Continue? ")


end if

end sub
this code is in the HTML page( i.e .aspx ) of the project !

now I want to use the return value of the messagebox in the
(aspx.vb )



My problem is thus I can't seem to figure it out, how to transfer the value of IntResult to
If intMSgReturn = 6 Then
For Each obj In Panel2.Controls
If TypeOf obj Is TextBox Then
If obj.GetType.ToString.IndexOf("TextBox") > 0 Then
For i = 0 To 1

obj.visible = False

Next
End If
End If
Next
End If

intMsgReturn is a Public variable I have declared in a Module Called modgen

Now my question is this, is there a way I can declare a Session variable in global.asx and supply a value to it in my VBSCRIPT code in .aspx, that I can read in my VB.NET code so I can do some manipulation work , on the rendering purposes

The reason why Is that I need to ask a question and use the Message box to obtain the answer,

Now Before anybody tells me I should use "JavaScript", no I don't need to as this is an Intranet application, and we only use MS software, and IE.

Any Answers??

To do this requires a little trick with using the old HTML control called HIDDEN input. Apply the following:

ASPX file:

<% ..... CodeBehind="..." ... %>
...
<BODY ONLOAD="javascript:return GetInput()">
...
<FORM NAME="Form1" .... RUNAT="server">
<INPUT TYPE="hidden" NAME="confirmData" VALUE="">
...
</FORM>
...
<SCRIPT LANG="JavaScript">
function GetInput()
{
document.Form1.elements["confirmData"].value = confirm("Display Controls?");
}
</SCRIPT>
</BODY>
...

Code-behind:

Private Sub Page_Load(.....)
If (Page.IsPostBack) Then
Response.Write("Your previous answer was '" + Request.Form.Item("confirmData") + "<BR>")
End If
End Sub

Good Luck,

Yup .. can't mix JavaScript and VBScript code. I replied you PM with the code for VBScript.
