Prevent Button Serverclick Firing On Every Page Refresh?

Feb 22, 2012

prevent a button serverClick event from firing on page refresh?


<INPUT id="btnGo" type="button" value="Go" runat="server">

Public Sub btnGo_ServerClick(ByVal sender As Object, _
ByVal e As System.EventArgs) Handles btnGo.ServerClick

The btnGo_ServerClick function needs to fire on the button click, but not on page refresh.I've tried using IsPostback, but that is always true- even on the button click.N.B. I'd rather not go into the reasons behind why I'm using a serverclick, rather than an asp:button and a click event. Suffice to say it just isn't suitable for I am doing.

Whenever I request a page, the Page_Load on the aspx page appears to be called twice, so does the Page_Load on and user controls added to that page.

Evaluated.LoadContainer.Load(Page Page, HtmlDocument HtmlDoc)?

Jan 5, 2011

I have a page to which i send some variables with the GET method. In my VB back-end i get those variables using Page.Request.QueryString("<name>")If i then use the IsNumeric method to make shure it is an numeric string i get True back as value.

When i then try to transform the string to an Integer using val, cìnt, Integer.Parse or cType I get an error saying that my string could not be converted to a integer.So i made an error page which gives me all the info i need to deal with the problem (view below) Exception Message: Conversion from string "" to type 'Integer' is not valid.


IsNumeric confirms that it is a numeric string and that it should be convertable to an Integer. So why won't it work. I don't think that my code should provide any extra information because it only gets the querystrings, uses IsNumeric and then tries to convert them.

Aug 7, 2009

I have a master page which contains everything that inherits it within a form. A page inheriting from it needs to run some javascript to act on a text field on a page. However, I can't seem to reference that text field through the javascript, since the form begins on the master page. The following line will come up bogus: document.form1.txtFindUser.value = blah.responseText; This is because form1 is defined on the master page, while txtFindUser is on the current page.

Prevent Page Scrolling After Postback?

Apr 13, 2012

I am working with adding up user's scores based on their checks in a CheckBoxList. Every time a user checks a box, a value, X, is added to the overall score. When a user unchecks a box, a value, X, is subtracted from the overall score. No problems here.

The problem that I am having is that using the AutoPostback option in the CheckBoxList properties forces the page to load back to the top instead of staying where the user was situated, which means that they have to keep scrolling down after each check/uncheck. Is there a way to prevent this?

Page Events In Master Page And Content Page

May 11, 2011

The thing is i have a Master page and a Content Page. I have a LoadComplete in Content Page and a PreRender in Master Page. The problem is one of my htmlcontrols on content page i change on the LoadComplete event server side of the content page. I also have some code for disabling controls on the Master Page PreRender event. For some reason all controls on the aspx side go through the Master Page prerender except the ones that i change on the LoadComplete side. How can i make sure the entire content page loads and then the Master Page PreRender event is called, making all the controls go through that event.

Nov 15, 2011

I have a web application built around a frameset. The main page (with the frameset layout) is index.aspx. After the user logs in, if there are any alerts it redirects the main content frame to an alerts page with a confirmation button on it. When they click this button I want the index.aspx to be reloaded. If I use the response.redirect("index.aspx") on button click it reloads the main content frame with another frameset.

The server-side button click sets a flag within the database so that the user doesnt see the alert again.

how do I force a complete reload of the entire frameset?

Why Is A Row Added To Session Datatable Disappearing On Refresh Of Page

Feb 25, 2010

I have set up a class as a facade to access the session variables for my app. In this app I store an entire dataset for a particular employer as a session variable.Within one of the sub pages I have a button that adds a row to an existing table stored in that dataset.

Dim curRow As Data.DataRow = mySession.tWorksiteOtherMeasures.NewRow()
curRow("lngWorksiteID") = getSelectedWorksiteID(getSelectedSiteID())
curRow("strMeasure") = ""
curRow("lngStatusID") = -1


When in the code to add the row the row count increments and the row exists. Once out of that scope the page refreshes due to the button being contained in an updatePanel. When that happens and I click the add button again the row counts for that item reset to 0 and 1 after the code runs. The previous added row is gone.Here is how the Dataset is assigned from the web service:

Public Shared Sub loadDSEmployer(ByVal strUserId As String)
Dim myService As New someservice.service
mySession.dsEmployer = myService.GetEmployerAndSites(strUserId, isInternal)
End Sub

Refresh Parent Browser Window On GridView Page Change?

Apr 17, 2012

I'm using; I have a popup browser window that contains an databound gridview with textboxes. It has an "Add to Order" button which takes the values entered and updates the database, then closes the popup and refreshes the parent. This currently works perfectly using window.opener.document.forms[0].submit();self.close(); in a RegisterScriptBlock

I now need to update the database on gridview page chage so that textbox values are not lost. I put window.opener.document.forms[0].submit(); into the PageIndexChanging event of the datagrid, but it does not refresh the parent window. Refreshing the parent window with the order lines helps the user see what they have already ordered. My update database method runs fine, just not the parent browser refresh. I also tried "window.opener.location.href = window.opener.location.href" to no avail.Refresh parent browser window on GridView page change?
