Detect If Back Browser Button Pressed?
Dec 2, 2010In my app, there is a grid that you can drill down. You can go back to prev view via some links but the back bowser button is not integrated to that, so that if you do hit the back browser button, it logs out of the app which I don't want. I would be happy if it would redirect to the first page. I think this part is what we need. [URL] this is the startpage.xaml, at the end there is the hyperlink - so maybe here I can see if the back browser is pressed ( there is no other place in the codes that would navigate out), and if this is pressed I can redirect to a different spot? Is this a sound idea and how do I check if this back browser has been pressed?

View 1 RepliesC# - Prevent Opening Of Application On Browser Refresh?
Dec 19, 2010I have an ASP.NET/C# application that exports some data into an Excel spreadsheet using COM interop at the click of a Button control. When I click the button, Excel is opened with the generated spreadsheet. For what it's worth, here is the button code:
<asp:Button ID="export" Text="Export to spreadsheet" runat="server" OnClick="Export_Workbook" />
This works fine, except when I click the button, close the subsequent spreadsheet, and refresh the page. When the page is refreshed after clicking the button, the call to Export_Workbook() is made again and so the spreadsheet opens again. Firefox, for example, says this when you refresh: "To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier." This is something I want to avoid.
I'm sure there's a better way to accomplish what I'm trying to do, I'm just not sure what the best approach is.
Edit
I've accomplished this by doing the following:
protected void Export_Workbook(object sender, EventArgs e)
{
Response.Redirect(Request.Url.AbsolutePath, false);
ItemList.Prepare_Workbook();
}

View 4 RepliesWeb Forms :: Refresh A Page When Restarting The Web Browser
Dec 1, 2010 have looked around for an answer to this but not quite found what I need.
The main (home) page of my web app has a field on it indicating the last time an SSIS package was run. This is done under the page load event and the code reads a sql server table to pull of the date and time.
The problem is, if the date and time is updated and I then close teh web browser and re-open it and displays the main (home) page, the time displayed has not been updated. I have to either hit F5 or clear the temp internet files using the options under IE.
I found some code which refreshes the page automatically once every 5 seconds or at set intervals but this is not what I want to do. I just the page to be refreshed upon loading it.

View 1 RepliesAJAX :: Button Is Pressed On The User Control, The Events Are Fired But There Are No Changes In The Page
Aug 3, 2010I have an update panel on the parent page into which I load and remove a set of user controls.
Now, when a button is pressed on the user control, the events are fired but there are no changes in the page. For example:
Main Page
<updatePanelMain>
<childcontrol1>
<childcontrol2>
etc
ChildControl.ascx
<update panel 1>
<panel1/>
<panel2/>
<btn1/>
etc
So, if I want to hide panel 1 when btn1 is clicked etc, I simple use code such as panel1.visible = false.
All this gets executed but nothing happens to the page.
<asp:UpdatePanel ChildrenAsTriggers="false" UpdateMode="Conditional" ID="updatePanel"
runat="server" EnableViewState="true">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnSubmit" EventName="Click" />
</Triggers>
<ContentTemplate>
However, when I use placeholders instead of update panels in the child controls, I dont face any such problems.
