Mar 26, 2010
The program is written using dotnetnuke and c#
Im facing the following problem. I have a aspx page (test.aspx) where I have a form what I want to do is when I hit a button on the test.aspx I open another window (getCoordinates.aspx)where I do some things and create some session variables.
When I close the getCoordinates.aspx I want to call the page load of the test.aspx so I can make use of the session variables I created and fill some textboxes

I have a login page that is loaded in popup window (colorbox) and after user logs in it should be closed and parent window should be loaded with new page.
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Do While reader.Read()
If Trim(reader("ZAP").ToString()) = Trim(textBoxZap.Text) Then
Session("A") = "1"
Response.Redirect("~/default.aspx")
Else
lblErr.Text = "incorect"
End If
Loop
So once the buton is clicked and user name and password is corect popup window should be closed and user redirected to default aspx.

On my page: a Button1, a ListView1, a Panel1 and inside Panel1 an ImageButton1In the ListView1_PreRender-Event the property Panel1.Visible = false or Panel1.Visible = true is set.1. After first loading of the Page Panel.Visible = false ist set in ListView1_PreRender.2. After the postback click on Button1 the criteria for the visibility of Panel1 are evaluated, thus setting in the ListView_PreRender Panel.Visible = true.

In the UserControl I am adding dynamic ImageButtons depending on the condition When the page loads and I click on Edit button I have no problems and btnEdit_Click is fired. But after that (btnEdit id removed and btnSave is added) when I click on btnSave the btnSave_Click event does not fire. What could be the problem?

I have a DropDownList that fires off some server-side databinding in its OnSelectedIndexChanged event.
<asp:DropDownList ID="ddlGroup" runat="server"
AutoPostBack="True" OnSelectedIndexChanged="SelectGroup" />
Elsewhere in the page, some JavaScript opens a popup. When the popup is filled out and submitted, I want to use JavaScript to fire that OnSelectedIndexChanged event in the opener page. I found some other code that does something similar:
if (window.opener != null ) {
var cf = window.opener.document.forms['aspnetForm'];
if (!cf) {
cf = window.opener.document.aspnetForm;

I have an aspx page with multiple modal popups. These modal popups are trigger in the page behind code using .Show() and .Hide().
This is what I have in the .aspx page for the particular modal popup under discussion:
[Code]....
The example below demonstrates the type of calls I am making to the modal popup extenders. Basically using the Datalist item command, the datalist commands are responsible for triggering my modal popups.
[Code]....
They all work fine after postbacks except the "activityReport" case (the last one). The only difference with this modal popup is that it contains a user control and all the postbacks are happening in the user control. So the problem is that in the last case whenever a postback happens in the user control then the modal popup is close.
1. If I separate the modal popup and place it in a page all by itself and trigger it to .Show() through a button click in the page behind code then the modal popup doesn't close. See below example.
[Code]....
2. The button click event in the test page looks as follow:

I need a Slider that will only postback when the slider has been moved. Can this be achieved with SliderExtender?
I have a TextBox with autopostback=true, within an updatepanel within a usercontrol. The TextBox is extended by SliderExtender (default settings).
The TextBox's TextChanged event fires perfectly when the slider is moved (MouseUp - standard extender setting). The aspx page is partially posted back, and all is well.
However, if another usercontrol on the same aspx page causes a partial postback, the SliderExtender causes the TextChanged event to be raised - for no aparent reason. This is causing problems.
Is it possible to prevent postback unless the slider has actually been moved?!

I have a small website where I want to display a confirmation dialog after clicking on a button.
When you click the confirmButton the dialog appears. Then you can choose between Yes or No to either continue with the PostBack or to return.
Problem: The first time you get into the site all works fine. But after you click Yes to continue with the PostBack, no click event will be triggered anymore.
Here is some code.

I've created a UserControl that is dynamically placed onto my page during the Init event. It populates and works great, but I'm left scratching my head at how to retrieve data from it during a postback.
It's effectively a multipick combobox that is manipulated entirely using clientside JavaScript (I'm using jQuery heavily). Inside the control container element, I render an empty DIV element that contains all of the selected items. As the user selects items, I generate DIVs within that container DIV that includes some markup. Of interest to me on the server side are the contents of a couple of INPUT fields.
After selecting an item, the rendered HTML looks something like:
[code]....
I may be completely off track and this may actually be impossible (or a stupid idea). The only alternative I can think of is to emit actual ASP.NET controls and hook the built-in event handlers.

I have a need to improve the asthetics of the standard buttons .net churns out. I am fully aware of how to do this using css but I can only really style the button if I add a span element inside the button. Luckily the link button allows this so I have got the following which for usability i have put inside a user control.
<linkbutton><label>button text</label></linkbutton>
I have exposed elements so that I can set values from within my aspx.cs page, these are text, command name, command argument, ccc class etc.
As it is a generic control, I have added OnCommand='Button_Click" which fires the event in the control itself. The Button_Click event calls a method ButtonControls passing associated command name and arguments across. ButtonControls uses the name to call the appropriate function.
As these are all very generic buttons, so far so good, but I have a need to trigger button events that may not be generic i.e on a control I have buttons that do something very specific to that control. I also have a requirement to call functions which relate to specific controls on the aspx page. I have created a user control which encapsulates the link button control.
Click triggers > Button_Click > ButtonControls > MethodToCall
sometimes I don't want to call Button_Click just an event on the aspx page itself rather than my generic button handler.

In our application we need to handle browser close event. When a user directly closes the browser, we should give him an alert message and stop him by directly closing the window based on some conditions. This we have handled through body onunload event. The problem is we are getting the alert message but after showing the alert message the window gets closed.
Is there any way to stop closing the window on click of browser close event?
And also when the page is refreshed, the last performed action is getting fired again.

I have a 2 part question for web user controls: 1. I want to have an event fire in my user control, but have it be consumed by the parent page, like:
<asp1:Object id="objectMain" runat="server" OnClick="Click" />
Is it possible to do this? Or do I need to make a server control for this functionality? I have it being able to be set in the Page_Init, but I'd like to make it as similar to actual controls as possible. Also, if it is possible to access via the Events section under Properties, that would be good and 2. I am trying to register the web user control as an AsyncPostbackTrigger for another UpdatePanel. With the previous question in mind, is it also possible to set this via the GUI, or does this need to be set programmatically as well?

Background: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface.
Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work.
I placed breakpoints at the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers were triggered. On the second click, they fired.
Example of Button Definition (within GetAdministrationInterface)

I have all of my code into one ASPX file. Called Scheduler.aspx. I am using the DayPilot scheduler and the Obout Flyout. But i moved it all to one page to make it simpler. But one thing I am having probelms with is; when I save my popup it should close and refresh the page. And when I hit the close link it should close (which it does) and then refresh the popup when I click on it to open again (which it doesnt). Since I have this all on one form and I am calling the popup using the flyout I can't figure out how to do these.
My page is called: Scheduler.aspx
My Scheduler is called: dps
My flyout is called: EventFlyout
Right now I have the flyout opening from a label. So when I click on the label my flyout opens, I insert data and it saves to the database. But i have to close my browser and open another to get the data I just imputed to show.

I have a page that has a note to the user about the file they're about to download and a button to click to start the download. When they click the button, it does a Response.Redirect to another page with the following code in its Page_Load:
Response.Clear()
Response.Buffer = True
Response.AppendHeader("Content-disposition", "attachment; filename=" & FileName)
Response.AppendHeader("Content-length", FileSize.ToString)
Response.ContentType = "application/download"
Response.WriteFile(Page.ResolveUrl(FilePath))
Response.Flush()
Response.End()
I want the download to start and then I want this page (which is a tab in the browser) to close.
The code to download the file works fine. I just can't figure out how to close this tab when it's finished. I've read a lot of forum posts from people who are using similar code, but none of the suggestions seem to work for me. I understand that Response.End means that I can't put any more code this page; it will be ignored. But how do I get this tab to close?
