I am new to MVC. I created an application in which I am able to do login. I have used the basic template provided by MS. Now, I have to use registration template. But I need more fields than they have provided in their basic template. I am trying to add my fields manually on register.aspx, but its throwing an error. I tried to add a new content page in shared folder under view, but dont know how the event of register button will handle in controller.
I have a base server control class for all my user controls. Inside this class I have the following declaration:
[Code]....
Concrete user controls used in the application are used always inside a ModalPopupExtender object and the popup it is always handled with server-side code. This means that there are no controls binded to the OkControlID and CancelControlID properties of the ModalPopupExtender.
The responsibility to show the Modal Popup is then given to the aspx that has code like this in the ASPX file...
[Code]....
To hide the modal Popup the aspx just implement the event handler
[Code]....
Last, the event firing is responsibility of the concrete UserControl class that can use any way to do it's work and then fire teh event. This is done through this code:
[Code]....
The problem I am facing to is that in the OnItemSaved of the super class the ItemSaved EventHandler is always null and so the event it's never fired on the aspx page. Where am I doing wrong?
Can I fire a custom event in asp.net according to my needs ?
I am making a simple chat application for my website.
I am using cache variable to store my chat. When I submit my textbox cache variable updates and text is cache variable is displayed to both the users. Since , I get a postback , my page refreshes and I get an updated value of cache variable but the other user needs to refresh the page.
So, is there any method, which can check if cache variable has been updated and fire an event , so that , I can deliberately force the browser to refresh.
One more problem , I am want to list the online users of my website. ( I need to list all sessions currently active ).
I think , best possible way is to insert current date, time on database after every 10 seconds by all users. How can I get an event which can update a column of database every 10 seconds ?
I am creating a custom control. Let's say I'm reinventing the wheel and creating a custom Button control that derives from the UserControl class(only for example)
Well, it of course has a Click event handler. Now my problem is, when do I call this event handler? I know it happens sometime between the Pages OnLoad and OnLoadComplete, but I'm not quite sure what event I can hookup to so that the Click event is raised at the same time as other control events.
I am trying to create a simple custom control where in there is a image button on the control along with a label.
the problem that i am facing is that the image button appears just fine along with the specified properties. But somehow when i click on the image button it does not generate the click event. the page simply refreshes.
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 am trying out some code which enables me in creating a page with extension .asp2
The tags included will also be custom, something like:
[code]....
I have done the necessary changes so that ASP.NET identifies the extension. I have also kept a mapping of custom tags and asp.net/html tags with myself. With this I am able to render the page on browser. But how can we do event handling(usually done by page postbacks and code) in such a scenario?
I've got an website that needs to know when someone has closed a details page. Is there a way to fire a post back using Javascript to call a particular Sub or Function on the Unload event?
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
How can you refresh the 'parent' page when you close a 'child' window
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.
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.
I have a gridview and dropdownlist, let say the content of dropdownlist is YEAR and the content of gridview is Name and Year. Now for everytime I change the Value of dropdownlist the content of gridview will change but it will not load the page
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?
for some very special reason i want to click on a button in masterpage.aspx firing the event of code-behind without having reloaded masterpage.master.cs (starting page_load()).
Can not fire Grid View RowEditing event in page load?
I have a grid view , select the grid line item from popup when click the image button which is located in header template. When click the select button in popup window , fill up the grid row and allow to edit the quantity text box.
In page load If Page.Request.Params("__EVENTTARGET") = "ctl00_popupField" Then AddHandler grdDOLineItem.RowEditing, AddressOf grdDOLineItem_RowEditing End If Protected Sub grdDOLineItem_RowEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) 'bind the grid view row End Sub
I have one Datagrid with Footer. Footer Row Contains Input fields with one Button to add New Values. I have button click event but not getting fires. my code follows:
I have a button which has a click event but its not firing on the first click. I suspect its something to do with that i am in dropdown box control so when i click the Button the event for the dropdown box occurs (textChanged) but it forgets about the click event
Of course if i click it a second time it works.
Or if i click somewhere else first so that the event TextChange occurs and then click the Button the first time it executes..
Is this normal and what are more workarounds if any?
basically the TextChange event must fire but the button click event must fire as well.
All the events i am talking about are ASP.NET events.
here is some examples of the events i am using - both the button and dropdown
uxGetData is a button and uxToDate is a dropdown box
I have a DetailsView control bound to an ObjectDataSource within a User Control (.ascx). It appears that the DetailsView.OnDataBound event is being fired on every page load or postback.
I do not see this behavior with a similiar DetailsView directly placed on an aspx page.
I have two custom validators that are in the same validation group. This validation group is launched by one button. My question is, in what order will the custom validators fire in? It appears that the validator that is placed earlier in the aspx page fires first, but I don't want to rely solely on this.
I've written a custom ASP.net control that descends from LinkButton and overrides the Render() method. I'm using it to replace ImageButtons in the site I'm working on so we don't have to have an image for each button. This control works fine, does the required post-backs etc., however it doesn't fire the validators in its validation group. This is obviously an issue. The code for the control is (condensed) as follows:
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls;
Does anyone know why this would not be causing the validators to fire? I was under the impression that leaving all the other methods in LinkButton un-overridden would leave all the other functionality the same.
I'm building a library of custom controls. My controls are inherited from CompositeControl. Depending on the user's answer I have to insert more custom control. I have a PlaceHolder (_ph) passed in from the client code. I insert my controls into that PlaceHolder.
My problem is the control I inserted in the event handler does not fire its event, but it fires the parent event. For example, if I have an EddDropDown A, and the user picks an answer, I have to create EddDropDown B and C in edd_SelectedIndexChanged. When I pick an answer for B, it fires SelectedIndexChanged for A instead of B.
I think it has something to do with entering the page cycle late.
this is an example of my controls:
using System; using System.Collections.Generic; using System.Collections; using System.Linq; using System.Text;
I have an image on my page than can be changed from a fileupload asp.net control on the page, i want to provide and alternative to clicking the button by allowing the user to click their image. i gave the fileupload a class 'jqueryPhotoUploadTrigger' and it renders like this:
$(document).ready(function() { $("#clickMyColl").click(function () { alert("image has been clicked"); $('.jqueryPhotoUploadTrigger').click(); }); });
the alert does show so i know the script is firing when i click the image. i was just hoping the .click would fire the event on the button but it didnt. can i do it this way or must i find an alternative?
