I have a button, contained in a panel, with a click event, that works fine. However when a users presses another button, I need to move this button into another panel (this is actually a panel with a modalpopupextender), so I this code to do so:
newPanel.Controls.Add(buttonPanel)
It all get's moved and looks fine. However now when the button is clicked it doesn't fire the associated event. I have tried re-adding the event in the page_init, with this code
((Button)this.FindControl("serverModalSave")).Command += new CommandEventHandler(modalSave_Click);
But with no luck. How can I get this button to fire it's click event when moved, and why does it stop working when it's moved?
EDIT:
This Button needs to be added to a panel specified by the user at run time, so there is not a way to determine where the button will go in advance.
I could instead of moving this button, create a new one, but because this button is not created in the page_init I am having issues getting that to fire an event either.
Since i have 5 buttons that pretty much run the same code, except for the database updates, i found some examples of how to do this.. so i created 1 button event, and put my general calc code then some if statements to determine what button was clicked.. but doing this now i get a NullReferenceException
and here is the code its complaining about, why would this work within the other button events, but not this one? Ive compared and and all the buttons on the page are the same with the except of the database entries.
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 am currently developing an asp.net project. there is a previous, next, and cancel button that the user can utilize, but the problem is that everything is broken into controls so that if they hit the browser's back button it will reset everything and take them to the very beginning. i would like to capture the onbeforeunload event and trigger the previous button click event (i.e. treating navigation like clicking the previous button).
i have an form with an button and some input controls. some time due to input problem i may get error after that if i refreshed the page then that time the button click event has fired, how to avoid this kind of bad event fire.
I have a textbox with autopostback=true and a button to save the data in the form. Functionality works fine when entering a value in the textbox, tabbing out of the textbox and clicking on the save button. But issue comes up when entering a value in the textbox and directly clicking on the save button without tabbing out of the text box. In the second scenario, only textchanged event fires and save click event dosen't fire. What I was expecting was after exection of textchanged event, save click event should also fire. But this is not happening.
I am updateing my gridview using button click event but at the fisrt time it does not get updated first time but its works second time i dont know why . Dol u know how to genterate two button click event for the same button.Records never get updated on first button click event but its works on second button click event.

I have one Button (Refresh Button), One ComboBox (containing DEV and UAT as its items) and a GridView on my asp page.
I am filling up my Grid with values from database on the ComboBox's 'TextChanged' event and Buttons's 'Click' event.
First time when page is loaded, there is no information in the grid, but when i choose DEV/UAT from the ComboBox 'TextChanged' event is fired, the grid is filled with the relevant data. That is what i want.
When i click the Refresh Button to refresh the data again, first comboBox's 'TextChanged' event and then 'btn_Click' event is fired.
I want then when a button id pressed only 'Click' event to be fired and not the ComboBox's 'TextChanged' event.
In form I have added two radio button and on one radio button oncheckedchanged event has been registered but this event does happen only when i select the button and not when i select the other(The checked is changed).
I want a confirmation password message box on a click button event. if password is correct then it will perform some business rule action. other wise it will show a message you are authorised for it.the button will be server side control at the webpage home.aspx
is it possible to disable right mouse button click event of a link button. i know to disable it in entire page..but i want to disble it for some controls only.
The whole thing is in a form, and it doesnt postback when this button is clicked. Im no good with javascript, but i got a feeling thats not the problem.
in my ASP page iam using button and drop down list controls. In the button click event i have some process, and dropdown list change event have some coding. while iam clicking the button its not directly goto button click event, its going to dropdown list click event.
I was wondering if anyone had an easy way to wire up javascript event handlers to events happening on the server-side. I have a long running process that includes a lot of steps, and would like the client to be continually updated with new information as the steps transition. Will this involve some sort of polling mechanism?
I have a Web Form that contains a Web Control. This control has several buttons on it and one in particular requires that I click it twice before the Click Event fires. The settings are all the same for the buttons but just not sure what to look for.
I have a table with text box asking for Name and Address for reference. If need be, I would like the user to have the ability to add more and not be restricted to just one. How would I add a new table to a form by clicking on my "getMore" button?
