Asp.net - Simple Way To Detect Page Refresh/F5?

Apr 22, 2012

I have wasted lot of time in searching and finding the simplest way to detect a page refresh and when the user press F5 button on his browser.I have seen most of the samples provided on net but none of them could satisfy my needs.I will explain in a simple step way to understand my issue:

I am trying to use sessions and loading some images and storing them to folder.Next I have a button to process some operations on images.(Here I have a postback where I am trying to detect postback and savng them to the same folder.)Now here comes my issue now whenever user tried to refresh his page manually or by clicking F5 buton on his browser I need to load all the images again from the folder.Here is my code:

If Page.IsPostBack Then
//Here I am checking if the session is there or not.If it is already there I am adding images.
Else
//
Here I am creating a new session and adding images.

Asp.net - Detect F5 Being Pressed And Refresh?

May 25, 2009

I have a webform and i want to detect if F5 button was pressed or if the page was refreshed. I know about postback but it is not what i'm looking for. I have a gridview that loads in a modal popup when a button is clicked and a parameter's value is set for the gridview. When refresh is hit and if the modal popup button was previously clicked the modal popup is visible right after refresh. I want to detect if the page is refreshed to prevent this. any ideas? I thought to try Override but I'm not exactly sure how to use it. I tried Control.ModifierKeys but I don't have access to ModifierKeys.

Asp.net - Refresh Page With Framesets On Button Click

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?

Prevent Button Serverclick Firing On Every Page Refresh?

Feb 22, 2012

prevent a button serverClick event from firing on page refresh?

Markup:

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

VB.net:

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.

Refresh Page Back To Gridview Data At Previously?

Jul 29, 2009

I have three dropdown list boxes and a gridview. The gridview shows data based on what is entered in the dropdown list boxes. I have added a button that allows the user to insert a record into the database and then the page refreshes. The problem is that when the page refreshes the gridview goes back to whatever was initially in the dropdown list boxes when I first brought up the page. Is there a way to refresh and maintain the data in the list boxes so the gridview shows the same data? My code is below.

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

[code]....

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 ASP.net; 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?

Asp.net - Refresh DataGrid And DropDown On Main Page After Hiding Modal Popup?

Dec 7, 2009

I am adding records to a database from a modal popup. After hiding the modal popup, the page has not been refreshed (even though I have Re-bound the controls). I have reviewed a few postings on the web about this but the solution still evades me. I have attached my code after removing some of the extra detail.

It seems I need to cause a postback, but I don't know what needs to be changed. Some posts have talked about the extender being misplaced.<asp:Content ID="Content1" ContentPlaceHolderID="Head" Runat="Server">

<div class="divBorder">
<asp:DataGrid id="dgrSessionFolders" runat="server" BorderWidth="2px"
BorderStyle="Solid" BorderColor="#C0C0FF"

ASP.NET MVC AJAX Returning New Page On Simple Call

Jul 15, 2009

I'm not sure what's wrong with the following setup. I have a View that lists a number of records, and each has a dropdown associated with it to change a value on that record. I had it all working without AJAX, but you had to change a bunch of the dropdowns then click a Submit button. I wanted to change it so that it would save the dropdown choice immediately.

My stripped down View (of type IEnumerable(Of MyTable)):

<script src="../../Scripts/MicrosoftAjax.debug.js" type="text/javascript"></script>
<script src="../../Scripts/MicrosoftMvcAjax.debug.js" type="text/javascript"></script>

[Code]....

What I would like to happen is for the dropdown change to trigger the Update controller, but probably not return anything - just update the database and let the user move on. What's happening though is that a blank page is displayed with the Content value on it (i.e. "123: ABC"). It's the correct id/code combo, so the Update seems to be firing correctly, it's just choosing to wipe out the html.

Text File Writer - Saving The File And Refresh The Page

Mar 9, 2009

I have an asp page with vb.net code that will query a database and present the user with the number of records that exist that need to be exported along with a button to export them. After you push the export button, it will prompt for a location and filename. But after that, it will not refresh the page with the new counts that now exist. Or in this case update the count to zero for the button they clicked.
[Code]
So how can I tell the page to refresh with the new counts. It almost seems like I need to tell the process to wait until after the user has finished finding the location and saving the file but I don't want to add a generic threading.thread.sleep in, I want it to only wait until they are done and then refresh the page.
