I have a page books.aspx that has a control named authors.ascx.
Inside the authors control there is a "select" button I want to add some kind of listener or event handler (not sure of the correct terminology) so on the parent page (books.aspx) I can respond to the "select" button being clicked.
I have to pass the authorID from the user control to the parent page.
In my authors.ascx control I just created this event:
[Code]....
Now I need to write the function for SelectAuthorBtnClick and I think add some kind of listener in the parent page to listen and handle the event.
I have a gridview called gvResults. In the gvResults_RowEditing event I add a row below the one selected. In that new row, which spans all columns, I insert a user-control. There are two buttons and some textboxes in the user control.
My problem is that when I click one of the user-control buttons it never gets to the button event handler, I think because the user control is not recreated on the page postback. How can I have the user-control events fire before the parent page events fire?
I tried using an update panel, but I still get the parent posting back before the user-control events.
Is there any way for one user control to raise an event that is handled by another user control without going through the page? I am using Umbraco and do not have access to the page object.
--Edit--
Umbraco has the idea of Macro's (user controls) that it loads into pages. I can't access the page directly as this is part of the framework.
There is a publish subscribe (pubsub) pattern that I know would fit my needs well (2 user controls that need to talk to each other) but am unsure how to hook it up in ASP.Net without the page object.
I am loading in a user control on page load and events are never firing. The user control loads fine with the correct information. it contains two dropdowns and an
calendar control. The dropdown selection changed event is never fired. I am not sure if there is something wrong while control is being rendered.

I created two instances in a page. The first instance fired up imgMensaje_Click without a problem, but the second one event doesn't fired up at all.

Event's code:

WUC instance:

Setting a breakpoint on RaiseBubbleEvent, when i click firs't imagebutton event fires up, but when click second0s imagebutton nothings happen.
Currently have Main.MasterPage, a MyNewPage.aspx (with master page file) and a use control with buttons. Should I load the events in the MyNewPage.aspx during the Page_load or during the InitializeComponent() ?
Example: MyNewPages.aspx (HTML)

Or Should I do this??

I have a user control that will basically be a header in most of my pages, but not all. I want some code in the user control to be run before the page load event of the page that holds the user control, but the page load event fires before the events in my user control. Is there a way around this?
View 3 RepliesI have a web page where I'm dynamically loading one of a series of user controls. In each user control I call a general-purpose event to inform the web page that data on the user control has changed and/or new data is available. On the user control I define the Event Handler like this: public override event EventHandler DataOut_Handler; and then I force the event to occur like this:
DataOut_Handler(sender, e); On the web page I reload the previously loaded user control and wire up the event handler like this:
protected void Page_Init(object sender, EventArgs e)
{
DataEntryUserControlBase userControl = (DataEntryUserControlBase)LoadUserControl();
if (userControl != null)
userControl.DataOut_Handler += new EventHandler(UserControl_DataOut_Handler);
}
Note: It's "DataEntryUserControlBase" rather than "UserControl" because I constructed an intermediary base class to making casting simpler. Everything seems to work fine but I do have a question: When I step through my code, after the last line in Page_Init is executed I move the mouse cursor over top of userControl.DataOut_Handler but it reads null. The code is working fine but I'm most curious why I don't see any object associated with that item immediately after wiring up the event handler?
If not what are alternatives in asp.net mvc to make reusable components? Which of those alternative is recommended to use?

I got a problem when raise an event from a button in web user control, it seems not work!!!
I dunno how to fix it, is there any1 got the same problem?
I have a page called "EDIT.ASPX" on that page it has come TextBoxes, Label and 3 User Controls. When the Edit.aspx page is loaded all the correction form Controls are loaded properly, even the User Controls loads with no problem. The problem that I am expericing is that on the User Control I have a CHECKBOX with AutoPostBack="true". Each time the user click the CheckBox the User Control disappear. NOTE: How do I fix this problem and eliminate my page control from vanshing. The user control needs to keep the same state as the Edit.aspx page when the checkbox is clicked. I need to be able to click the checkbox without loosing any data on the page rather it's the Edit Page or the User Control.
View 5 RepliesI have a custom ascx user control on my page that includes a dropdownlist. There is an onSelectedIndexChanged event handler that is connected to this dropdownlist. The first time the user selects a value, the page does a postback and the logic executes correctly. However, if the user then goes to change their selection, the event handler does not get triggered.
View 3 RepliesI have the following problem. I have a user control with its own events and procedures. I added this control to a page programmatically. It appears as it should but when you click a button on the user control. the control disappears from the page.
View 6 RepliesA little confused on something. I have a User Control in a master page. In the User Control there are image buttons. when I try to wire any click event even to say update a label in the User Control itself, nothing gets updated.
It is as if the postback is not handled at all.
What I want to do is click the image button in the User Control and then change a value in the master page. This could happen a few ways but for example it could update a public property or a control itself like a textbox or label.
I am using asp.net membership and the login control. I would like to prevent a user from logging in with the same use rname if they are already logged in. I would like to place code in the LoggingIn or Authenticate event of the login control to check whether the user is login and prevent them from logging in again. Any ideas on the best way to do this?
View 22 RepliesCan i bind and call the user control directly on click event of link button? instead of binding user control in another aspx page and then call it to the masterpage's link button click?
or else can i bind user control in a page lets say default.aspx and then call it in two different master page and show different functionality of it according to the masterpage its getting shown?
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.
I have a user control with two drop down, on selection change of first dropdown second dropdown should get populated. Now when I place this user control in a aspx file, I need to access the second dropdown value on change of send dropdown .
eg: in ascx file
Department drop down and employee dropdown. on change of department dropdown, employee dropdown should populate. (which is working fine for me)
in aspx.cs file
on change of employee dropdown, I need to get the employee id and so some other operation. (I am struggling here)
Is there any way where I can fire usercontrol event from aspx.cs file?
I have a webdayview control (Infragistics proprietary ASP.net control) on my page. On the aspx source I've inserted some javascript (webdayview_click - clientside click event) that calls a webmethod in the codebehind. This seems to work fine, but when I
insert this webdayview control into a user control and move the corresponding javascript into the aspx of the user control, it doesn't work. I can't even insert a breakpoint into the javascript function to debug it. Is there a way to make it work? I want to enable the click event of the webdayview control so that when I click on it, the javascript function calls the webmethod. Here's my code (remember it is inside a user control):

I posted this question on the Infragistics forum but didn't get any replies. Hopefully I'll get some here. :)
I've run into a problem with one of my web sites and I am having trouble figuring out the problem and a good solution. This is my scenario: I have a user control that displays a slideshow with images and some text that changes every fifteen seconds. To do this, I have an update panel that contains a timer control with an interval of 15000. It calls a method called slideshowTimer_Tick in the codebehind. The web page that contains this user control is a relatively simple page; no update panels or timers, just divs.
The problem I have is that if I have two of these user controls on the page, the tick event only fires for the first control. It never fires for the second control, although the control is full initialized otherwise.
I have a user control that displays some database records when I first hit the page. When I click the submit button the page load event fires again, loading the user control again. Then the button click event fires inserting a new row in the database which is not shown on the page because the user control already did its stuff. If I could get the user control to do its stuff after the button click event I could then see the newly inserted row. I can do this by pulling the code out of the button click event and sticking it in the page load event. However, I think that would be bad code flow. How can I get the user control to do its stuff after the button click event has fired?
View 7 RepliesI 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?
On my master page , I have "Search textbox" and "Search Button".
On My content page , I have a "User Control" which has a "GridView".It shows some data about Vendors.
Also, on this User Control's Page Load, i have code written to display all vendors in GridView.
Now, when user enters Vendor Number in "Search textbox" , and hits "Search Button" , i want to handle this event inside my User Control.
