Changing Control Property from another Frame

Wandha · August 6th, 2003, 10:32 AM

I sent this question earlier today, but I am not sure it went through. If it did, ignore this.

I have a page in ASP.NET with two frames - Frame1 and Frame2. I would like to change a property of a control in Frame1 as a response to a click event on a button in Frame2. Can someone help with VB/NET script.

Thanks you.

u should use JavaScrupt for this! (as I know)
this is a sample to change a color of Frame2's BG from Frame1.

Code:

var windowObject = window.parent.frames["Frame2"];
var newBGColor = document.frmColorChanger.txtBGColor.value;
windowObject.document.bgColor = newBGColor;

Hello HTH,
Thanks for your response. I am sure by now you know I am new in this area. Please help me further. The question is: "How do I use JavaScript in my VB.NET page. Do I put it on the OnLoad event. But there is already an OnLoad sub in VB.NET. Please help me here.

Have a nice day.

Michael.

Hi,

If You can use script for page, use RegisterStartUpScript:

public Sub Page_Load(Sender As Object,e As EventArgs)
      ' Form the script to be registered at client side.
        Dim scriptString As String = "<script language=JavaScript> function DoClick() {"
            scriptString += "showMessage2.innerHTML='<h4>Welcome to Microsoft .NET!</h4>'}"
        scriptString += "function Page_Load(){ showMessage1.innerHTML="
        scriptString += "'<h4>RegisterStartupScript Example</h4>'}<"
        scriptString += "/"
        scriptString += "script>"

             If(Not Me.IsStartupScriptRegistered("Startup")) Then
      Me.RegisterStartupScript("Startup", scriptString)
             End If
   End Sub

For contol on page, you can use Addatributes:

control.Attributes.Add("onKeyDown"," your javascript")
