Web Forms :: Dynamically Created Button Click Event Firing?
Mar 8, 2010
I am creating two buttons within the StoryGet() method, first when the page loads. When one of the buttons is pushed, lets say the left one - I want to call another method - "ButtonLeft_Click"
Ive used this same solution in other sites and it worked. With this solution, click event never fires.
If I move the StoryGet() call from Page_Load to PageInit() the button event fires, but because this event also calls StoryGet() the method runs twice, which I don't want.
I tried adding this to page_init so the original StoryGet() method only gets run the first time the page loads unless the method is called directly but then the page loads, but the button click event doesn't run again
if (!this.IsPostBack)
{
piccount = 0;
StoryGet();
}
Their is placeholder inside update panel to which i add my dynamicaly created a div which contain a link button (dynamically created). When i click link button div get disappear and link click event is not fired
im creating a button control in page int and im assing a click event for the button control. here the click event is not firing for the first time. here is my code.
I'm trying to create a button dynamically with event by original button. The original button's click event response creates a button. The new button has a click event attached with a test message.What I have to do is onclick change background color of dynamically created button and grab id value to delete when button delete is clicked. Unfortunately, when I click the dynamically attached button, nothing happens.
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]...
I have a accordion control inside an update panel. As I loop through the Products table and the Details table in the code behind, I'm creating the accordion panes that will display the data. There's an "Add to Cart" button created for each product (each accordion pane), and I'm asigning an EventHandler for that button, but it never fires... Here's the code where I'm creating and adding the button to the page:
[Code]....
[Code]....
[Code]....
And here is the code event that is suposed to fire:Private Sub addToCart(ByVal sender As Object, ByVal e As CommandEventArgs)
Am adding a sample webpart dynamically in which i add a Button Control.the isssue is Event is getting fired when i Click on the scond time and the other issue is the web parts are getting duplicated for each postback.
My page contains a button [Button1].I've dynamically created a new button [Button2] in the Button1_Click event and and assigned event handler also.But when clicking on Button2, Button2_Click event is not fired.I think its because the page looses dynamically created Button2 after post back, since it is created in Button1_Click event.Is there any way to maintain Button2 on page and raise Button2_Click 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.
I have a webfrom on which I have some textbox controls, validation controls and button controls. When I click the button is validating the form but when I fill the text boxes with valid data and click the button nothing is happening i.e. the page is not posting back and button_onclick event is not firing. Below is the markup.

Does anyone have a good vb example of adding an "onClick" event to a button that is dynamically added into a templatefield of a gridview. MSDN just says to use the addhandler statement with no other good info for a 'dynamic' scenario:
I have a UserControl, which has few textboxes, RequiredFieldValidator and a submit button. Every thing was working fine and now suddenly the button click event stopped working.If i set the CauseValidation= false for button, then it s working fine, but i can not do that because i want user to enter some value in the textbox.I investigated that it might be RequiredFieldValidatoe which is stopping the button to postback, but why its doing like that if you have entered the values in textboxes.
I have a aspx page, default.aspx, with an user control in it. Inside the user control (UC 1) there is a DataGrid. When the DataGrid is loading data with ItemDataBound, I need to dynamically load another user control (UC 2) for each row in the DataGrid. UC 2 has a Button ( BTN )with an eventhandler associated with it in code behind.
User control loading is fine, and the Button, BTN, is there. However, when I click the Button, the eventhandler is not reached, not firing, even though the page does postback. I googled for this issues, and I know the dynamically loaded user controls need to be loaded every time the page is postback. In my case, it needs to be loaded each time the datagrid is doing ItemDataBound. I did it and even hook up the eventhandler with button click event each time when the user control is dynamically loaded. I set EnableViewState to true on the Page and controls.
The following is part of the code from UC 1, AcctPaymentDetail is UC 2 in the code.
I have Onclientclick event attached to the button in serverside code like below,
[Code]....
Also, the onClick event is attached for the same button in the aspx page,
[Code]....
The serverside click event should fire if the onclientclick javascript function return true. The "ValidateData()" function is called to validate the entries in the form. This code is working fine in IE. But in Firefox, both events are not firig. If I remove the line "TopPanelButton.OnClientClick =..." then onClick event is firing.
Here is what i am trying to do I have a multiview and two views in it so based on click event the link the views change
[code]....
apparently they are not firing on first try. The reason i am doing this is the two views have tables with different images to be used in building my menu.
What am i doing wrong? or why is the click event firing on second try?
I have a grid view in Ajax UpdatePanel. In a column of a grid view I have a button call btnAddNewRecord. I need to fire btnAddNewRecord.Click event once I click on that.
I have Onclientclick event attached to the button in serverside code like below,TopPanelButton.OnClientClick = string.Format("if(!ValidData({0},{1},{2},{3})) return false;", txtOD.ClientID, radCmbOD.ClientID, txtgetMe.ClientID, RadAjaxLoadingPanel1.ClientID);Also, the onClick event is attached for the same button in the aspx page,
The serverside click event should fire if the onclientclick return true. The "ValidateData()" function is called to validate the entries in the form.This code is working fine in IE. But in Firefox, both events are not firig. If I comment the "TopPanelButton.OnClientClick =..." code then onClick event is firing.
i created dynamically a table with in a function... this table is added to a panel. and this panel is in ajax updatepanel... statically i have given no of rows as 3, for that table... in page_load my table with 3 rows is created.... but i cannot identify this table in another button click event...
I have a master page containing a ScriptManager control, and a Content Page containing a ScriptManagerProxy Control. Further on the content page I have an UpdatePanel control containing a GridView control and a server side button control. I have registered the button control as a trigger with the UpdatePanel control asynchronously and have set the UpdateMode of the UpdatePanel to "Conditional". I also have a "JumpLoader" control which is outside the UpdatePanel control. I have the following event for Jumploader wired up through Javascript. I am pasting the relevant sections of the code below:
I have textboxes being generated by a repeater that use OnTextChanged with autopostback enabled so that I can know when when the values change. This all works perfect.The problem starts when I try to click on any buttons on the page. The loss of focus triggers the event for the OnTextChanged; however, the event for my buttons never get fired. I checked this in the debugger and while debugging if I put a break-point in the page_load it will call both; however, without the break-point it still only calls the OnTextChanged event.I found this post on JavaScript. If my problem is also JavaScript related, why does the clicking of the button fire in debug mode?
I'm dynamically creating a table on my page with rows and controls. It looks like a gridview but it's not (it should've been, but too late now, seriously). I have a first name, last name, date of birth, etc. I want each row to have a button to add rows underneath it. So I create an event handler each time I create a new row and assign it to the click event of a button contained in the row. But it's not getting called.
Is it correct that the event handler doesn't stay established because the buttons are dynically created and are lost when the page posts back?
I have a GridView control bound to an AccessDataSource. After selecting a row I'm creating a table inside the selected row. I'm adding Buttons to this table. Their Click event never gets fired. I read about recreating the buttons and stuff, but still no luck solving the issue.
I have two asp.net buttons in my page.If i make button cause validation false then am able to fire button click event on server side but not able to validate text box values(but i need to validate text boxes) using required field validator.
