No Postback Just Open Another Page

[Art Cabot]

ASP.NET Newbie Question:
I have buttons (<asp:button) on my page that I want to just open another
page (including some arguments from the original page), just like would
normally happen with the "action=" on a form. I can't seem to get it to stop
posting back, the HTML source always shows "action=original page", regardless
of what page I set the "action =" to.

Am I missing something really obvious here?

Hi Art,

An ASP.NET page always posts back to itself, so that's the issue you're
encountering. Setting the action page doesn't help.

Try this to pass a value from one control to a second page:

1. Create a new page called btntrsfr.aspx and drop a Button and Textbox on
it.
2. Use the following code for Button1's Click event:

Private Sub Button1_Click _
(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
Context.Items("txtValue") = TextBox1.Text
Server.Transfer("targetpg.aspx")
End Sub

3. Create the target page called targetpg.aspx .
4. Add a label control to the page.
5. Use the following code for the page's Load event:

Label1.Text = CType(Context.Items("txtValue"), String)

You should be able to type something in the text of btntrsfr.aspx, click the
button and see the text show up in the label of targetpg.aspx.

Let us know if this helps?

Hello Art,
Please note that you can still use the HTML controls as <input
type="button" onclick=""> and you can set the action of the form then
submit to the new page.
This is more like a workaround but it will achieve what you want.
