I am dealing with a situation where I have a linkbutton which fires a ClickEventHandler.
<asp:LinkButton ID="LinkButton1" runat="server" CommandArgument="LinkButton1" OnCommand="lb_Command">LinkButton1</asp:LinkButton>
public delegate void ClickEventHandler(object sender, CommandEventArgs e);
I am adding numerical page links for paging of a repeater. I have used on of the numerical paging samples as my base. It works fine if I have less pages than my maximum total links. Eg if I have 11 pages, but only showing page 1-10 plus a next for the 11th, I get an error about duplicate control ids. I changed my control id to use a Guid in the string to keep it unque, after making this change the event handler never fires
private LinkButton createButton(string title, int index)
LinkButton lnk = new LinkButton();
//lnk.ID = System.Guid.NewGuid().ToString("N") + "_" + index.ToString();//Event does not fire if I set ID with Guid
[code]...
Problem : I have Added One Link button to the above Table.. Click Event for That Link Button Is not Firing Now. when i click on link button of table event is not firing at all.
LinkButton lbs = new LinkButton();
lbs.Text = "Submit";
lbs.ID = "lnksubmit"; lbs.Attributes.Add("runat", "server");
lbs.Click+=new EventHandler(lbs_Click); tcsp.Controls.Add(lbs);
tr3.Cells.Add(tcsp);
tabspilit.Rows.Add(tr2);
void lbs_Click(object sender, EventArgs e)
{
throw new NotImplementedException();
}
I am using the following code to load user control on to ASPX Page, which under a Master Page:
[Code]....
The user control name is passed as a parameter on the URL.
Inside the user, there is a LinkButton. The link button has a simple server side code for OnClick event.
Everything is working fine on the production machine, but, on the Development machine, I can see incorrect behaviour. I have started making some development changes on the Development Machine since several months back, and it will be very difficult to find out what caused the problem.
When I click the LinkButton inside the user control, the user control is removed from the parent page, and the OnClick event of the LinkButton is not firing.
I did debug, and found out that after I click on the LinkButton inside the user control, then the Page Load events for the master page and the ASPX page are working fine, and the IsPostBack is set to true, but the OnClick event of the LinkButton is not firing.
Very new to ASP.NET (using C# behind) and am having trouble figuring out the following scenario. I have a DataList that is populated (code below) and wanted each cell to be clickable. When the cell is clicked I wanted to know the unique ID for that cell. In my code behind, my OnClick method looks like this:
[Code]....
However I never get there. It seems as if the linkbutton always refers to some javascript callback function and just reloads my form. Am I using the wrong control for what I want to do? From this click I want to look up more information from the Key (will roll up the datalist or set visible to false, then supply the new data on the same page)DataList:
[Code]....
<asp:DataList ID="listSearchResults" Border="1" BorderColor="Black"
Gridview is not working when firing event from templatefield linkbutton
[Code]....
I have the following Jquery function to notify the user with a prompt when they have unsaved changes (similar to how SO does it) and are trying to leave the current screen.
<!-- in my aspx page -->
<script type="text/javascript" language="javascript">
window.onbeforeunload = function()
{
if (HasPendingUpdates())
{
return "Changes you have made will not be saved.";
}
}
</script>
This works as expected and shows the message box when the user tries to click a href to browse away or use the back button etc. The problem I am having is that one of my links is a asp:LinkButton because it needs to fire off some server side code before leaving the page. When the user clicks this LinkButton they get the prompt twice.
Scenarios:
User clicks the LinkButton
Prompt appears and user clicks the cancel button.
Prompt disappears and user is still on screen. GOOD.
User clicks the LinkButton
Prompt appears and clicks the OK button.
Prompt disappears and the same prompt shows again.
User clicks OK again.
Prompt disappears and user moves to the next screen and all is good.
So why am I getting the second prompt??? How is the OnBeforeUnload firing twice?
I have a web application I am working on that uses a master page. I am reading I create a LinkButton in the codebehind file for the page. When the link is clicked on the webpage, it does not even call the method defined for it. I have tried multiple ways of doing this and nothing seems to work for me. The page that has the link is also the page that will display the data for the related record. Can anyone provide me with a way to get the linkbutton to call the method?kButton is created and added to a dynamic table on the page
/* setup a link button to display the member name
* and add the cell to the row */
LinkButton
memberLink = new
LinkButton();

I've placed a link button control on my web form and added the click event to the code behind automatically), but I've placed a break point and it never hits it. If I do the same thing with a button it works just fine.I've searched for this problem and none of the results seem to answer why mine isn't working. Maybe I'm just missing something?
View 17 RepliesI have a problem with my Linkbutton which is not firing the RowCommand of my gridview.
Just for an Idea what I am doing is a follows:
1. WebForm
WebForm hosts UserControl_A.
2. UserControl_A = UpdatePanel + Panels + Gridview1 + CollapsiblePanelExtender
Updatepanel of UserControl_A consists of multiple Panels.
Each Panel consists of a Gridview1.
Upon each Panel expand UserControl_B is loaded.
3. UserControl_B = Details View & a couple of Linkbuttons in GridView2
Upon clicking the Linkbutton, unexpectedly it makes a refresh for the entire UserControl_A.
But it does not fire the RowCommand of its parent GridView2.
when i click the link button in Masterpage the window has to close. This function is working properly in IE but in fireFox or chrome or Safari Other than IE in all browsers postback is happening.

I have two problems with a databound AJAX Accordion. The Accordion looks like this:
[Code]....
The code behind has this subroutine:
[Code]....
[Code]....
The first problem I'm having is that this subroutine is not fired (I have a breakpoint in it) when the LinkButton inside the accordion is clicked. The Page_Load event fires and there is no error message, javascript errors, etc, but nothing else happens.
The second problem is that I'm not sure how to go backwards with the databind. I want to be able to make use of the UpdateMethod in the ObjectDataSource because I also have textboxes inside the accordion. I will have a Save subroutine that can be called but I'm not sure what code to put inside it.
I have a form action in an ASCX page set to an external URL
<form id="fLoginForm" runat="server" action="http://external.url" method="post" defaultbutton="bSignIn">
Inside there is a standard ASP linkbutton
<asp:LinkButton CssClass="btn" ID="bSignIn" runat="server" Text="Sign In" OnClick="bSignIn_Click" />
The event "bSignin_Click" never gets fired when I have ction="http://external.url" set on the form tag. However when I remove the action, it works as expected. I thought for runat='server' forms, the form would always post back? I need to read the URL from the action attrib and then redirect to it with some hidden input values also in the page.
I am making an VB app where the user inputs links to articles. I then display the links within a ListView using LinkButtons. The LinkButton sends me to the page most of the time, but sometimes I get the following error:
Method Not Allowed The requested method POST is not allowed for the URL /index.htm.
Apache/1.3.37 Server at visualbasic.about.com Port 80
Hyperlinks seem to work fine, but I want to use the CommandName of the LinkButton. What's the problem?
Here is my code. I was using the HyperLink for testing.

DataSourceID="SqlDataSourceLinks">
<EmptyDataTemplate>
<span>No.....
I have as asp.net website the code behind is C#.
i my application Page load method is firing two time.
I'm constructing a LinkButton from my codebehind, and I need to assign the onclick to a method, and pass a parameter with it too. I have this so far:
LinkButton lnkdel = new LinkButton();
lnkdel.Text = "Delete";
protected void delline(string id)
I'm rewriting a Web Forms application as an exercise to learn some MVC skills.I have a number of LinkButtons on the original application which postback and raise a serverside event that rebinds data to a datagrid.
E.g.
Event handlers:
protected void lbtnOffset0_Click(object sender, EventArgs e)
{
[code]....
What I currently have in MVC is this:
<%= Html.ActionLink("CurrentYr", "Index", 0)%>
<%= Html.ActionLink("1", "Index", 1)%>
and
public ActionResult Index()
{
return View(MietController.GetMietByYearOffset(0);
[code]...
As the ActionLink renders an tag it doesn't postback so my overloaded Index() method isn't called. What are my options for doing this in MVC?
I'm inplementing the Cascadingdropdown control from the toolkit. That's all working fine. The user makes their selection from the dropdown and submits the page to return search results to a listview control.
However, I've noticed that all the dropdowns re-populate themselves when the page is posted back. There is no need to reload the controls on a postback, how can I stop that please as it's very annoying?
I have a button that has click event in my C#. This works great. However afetr pressing F5 to refresh the page I noticed the button event is fired. This occurs every time I click F5. I've added if(page.IsPostBack) and the method still runs.
Is there any way to stop method from firing when the F5 Refresh button is clicked?
Ive used code that will allow me to find a modalpopup control through code behind and then show it to the user using the Show() method.The code works perfectly fine in some of my pages but not in others!Ive used breaks in my codebehind and it does find the popup and it goes into the Show() method but nothing pops up ?

Is there a way to make this work?

I'm new to asp.net and I have quite an annoying issue. I have a masterpage and a number of linkbuttons to navigate through the aspx pages.
My problem is that when I click on a linkbutton than the one selected, it doesn't highlight the selected linkbutton, because postback has been initialized. Instead it highlights the linkbutton that I have specified in the Page_Load event.
I've tried to specify:

The following works just fine in Chrome.
<asp:LinkButton runat="server" ID="lbEdit" OnClick="lbEdit_Click">
<button type="button" class="edit">
Edit
</button>
</asp:LinkButton>
And here is the CSS for button and its subclass.
[code]...
As you can see, nothing special; just colors and beautiful things.
I click on the blue Edit button and it fires the OnClick postback just fine.... in Chrome! But if I do the same in IE8, it just does nothing; doesn't even detect a click.
I removed the tag and kept just the word "Edit", and it works just fine in IE8 as a simple underlined link; the postback fires.
So, Why can't IE8 accept anything within LinkButton?
I'm sure I'm missing something extremely obvious here, but at this point I can't see it so I need the help.Anyway, I've got a repeater inside of an UpdatePanel. As of right now, I've stripped it down to this, just to try and isolate the problem:
[Code]....
Whether I add the handler during itemdatabound or I add the handler within the repeater itself, it doesn't seem to matter...the event itself doesn't fire. The AutoPostback itself seems to fire, but the event itself doesn't.
I'm running VS 2008 and .NET 3.5 SP1.
I want to implement hit tracking in an HttpModule in my ASP.NET app. Pretty simple, I thought. However, the BeginRequest event of my HttpModule is firing twice for each page hit. The site is very simple right now...no security, just a bit of database work. Should log one row per page hit. Why is this event firing twice?
Moreover, IHttpModule.BeginRequest actually fires a different number of times for the first page hit when running for the first time (from a closed web browser)...3 times when I'm hitting the DB to provide dynamic data for the page, and only 1 time for pages where the DB isn't hit. It fires 2 times for every page hit after the first one, regardless of whether or not I'm touching the DB.
It's interesting to note that Application_BeginRequest (in Global.asax) is always firing only once.
