Hi
How can I cause a postback in code, e.g., without clicking on a button?
Thanks.

Surely it is possible but my advice u to use a link button set
style="display:none" and use javascript (click method) to raise click
event....

try document.forms[0].submit();

Page.GetPostBackClientEvent

It would have been nice if they had named it "Page.submit"

Well, it's not quite that simple. You use this method to get a block of javascript
and then you have to attach it somewhere in the rendered HTML (typically
in some client side javascript event). Once the client side event fires,
then it will execute this javascript which triggers the postback.

Microsoft .NET Framework works at server side.
Javascript works on client side.

You should use javascript to submit form. For instance,
<a id="s">a</a>

at javascript code,

s.click()

I love the way .net has made things so easy

Its complicated. I consider using another approach if possible.
Good luck.

I would like to ask the same question.

I call a class called OpenPopUp:

OpenPopUp(ddlName, "Select_A_Name.aspx", 250, 250)

and this procedure is:

Public Shared Sub OpenPopUp(ByVal opener As System.Web.UI.WebControls.WebControl, ByVal PagePath As String, ByVal width As Integer, ByVal height As Integer)
' Pop up with controlable window attributes.

Dim clientScript As String
Dim windowAttribs As String = ""

'Building Client side window attributes with width and height.
'Also the the window will be positioned to the middle of the screen
windowAttribs = windowAttribs & "width=" & width & "px,"
windowAttribs = windowAttribs & "height=" & height & "px,"
windowAttribs = windowAttribs & "left=((screen.width - " & width & " )/ 2),"
windowAttribs = windowAttribs & "top= ((screen.height - " & height & ")/ 2),"
windowAttribs = windowAttribs & "status=yes, "
windowAttribs = windowAttribs & "scrollbars=yes, "
windowAttribs = windowAttribs & "toolbar=no, "
windowAttribs = windowAttribs & "location=no, "
windowAttribs = windowAttribs & "menubar=no"

'Building the client script - window.open, with additional parameters
clientScript = "window.open("
clientScript = clientScript & "'" & PagePath & "' , null,"
clientScript = clientScript & "'" & windowAttribs & "'"
clientScript = clientScript & ");"


'register the script to the clientside click event of 'opener' control
opener.Attributes.Add("onClick", clientScript)

End Sub


The browser does not popup this new window until the next post back.

If there is code that could cause a postback, I can possible place it
in my Page_Load event to cause this popup.

Is there code or way to cause a Postback in code?


Thank You'all ahead of time.
