Web Forms :: Dynamically Created Button's Event Is Not Firing?

May 26, 2010

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:

And here is the code event that is suposed to fire:Private Sub addToCart(ByVal sender As Object, ByVal e As CommandEventArgs)

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();
}

Web Forms :: Dynamically Created Buttons Not Firing Event On Click

Jan 26, 2011

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.

Web Forms :: Click Event Not Firing On Dynamically Created LinkButton

Jun 22, 2010

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

Web Forms :: Dynamically Loaded User Control Button Event Not Firing?

Mar 11, 2011

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.

[Code]....

And the following is UC 2 the is being loaded:

Web Forms :: Dynamically Created Button Click Event Not Fired?

Aug 12, 2010

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 ?

VS 2008 - Event Handler For Dynamically Created Button

Jul 31, 2013

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?

Code:
ImageButton addDependentButton = new ImageButton();
addDependentButton.ID = ADD_DEPENDENT_BUTTON_ID_BASE + currentSubscriberIDAsString;
addDependentButton.ImageUrl = "/Images/btnAdd.gif";
addDependentButton.Click += new System.Web.UI.ImageClickEventHandler(this.AddDependentButtonByRow_Click);
Control[] addDependentArray = { addDependentButton, addDependentDropDown };
WebControlUtilities.AddMultipleControlCellToRow(currentRow, addDependentArray, Constants.CSS_CLASS_TABLE_TEXT_NORMAL);

Web Forms :: Firing Click Event On A User-control That Is Created From Another Event?

Mar 1, 2011

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.

Web Forms :: Dynamically Created Checkboxes Not Firing Events Correctly

Apr 27, 2010

I've dynamically created 3 checkboxes as you can see in the code below. I also wrote an event handler below. When I run the code, the 3 checkboxes show up, but the event handling does not work right. Whenever there is postback from any of the 3 checkboxes, Label1 reflects the state of checkbox #3, no matter if I toggle checkbox #1 or #2. I put the code I have under Page_Init into Page_Load instead, but makes no difference either way.

The bottom line is, I want the event handler to know exactly which of the 3 checkboxes is firing the event so that Label1 can reflect that.

AJAX :: Dynamically Created AutoCompleteExtender Webservice Not Firing

Jan 6, 2011

I'm Creating some textboxes with autocompleteextenders attached to them dynamically at runtime however, I'm having some trouble getting them to fire.

When I create the textboxes with autocompleteextenders at design time, they work fine.

Here's the method that creates them both:

[Code]....

The txtID parameter is basically a name with a number appended to it, IE: txtBox_0,txtBox_1

The svcMethod parameter is of course the respective service to call (there are 2 different services.)

Web Forms :: Event Not Firing On Dynamically Added Control

Feb 23, 2011

While I am using a "Telerik" control here it shouldn't be any different I guess;

[code]....

What happens is that the control is created and rendered;

When I change value in the Combo box a Post-Back happens.

HOWEVER, the event RadComboBoxSelectedIndexChanged does not fire. Also when I am back at the page the new value is not saved; Obviously, i recreate the control every time. If I don't I get a ViewState error. Seems to me that there some ViewState management problem, but I cannot identify it...

Web Forms :: Dynamically Created Control Does Not Fire An Event?

Jul 8, 2010

I'm creating some linkbuttons dynamically and assigning properties like below. Also I'm adding an event handler to the created link button:

[Code]....

What happens here is when the links created at runtime are clicked, most of the links are linked to other applications. (e.g from app1 to app2, app1 to app3 etc..) So when moving from the current app to the next I want to abandon the current session. However, this event is not firing before navigating to the next page. Could someone suggest a workaraound or the correct way to accomplish that?

Web Forms :: Event Handling Of Dynamically Created Combo Boxes?

Jan 18, 2010

I am creating n number of Combo boxes dynamically at run time and adding a Handler of Combo1_SelectedIndexChanged() to the combo boxes.

At run time, When I select an item from one of the Combo boxes, the event fires n times rather than 1.

So for example : If there are 5 combos created, and I select an item from my first combo, the event Combo1_SelectedIndexChanged() , fires 5 times and that is an issue for me. How can I restrict this to run only for the combo that I selected.
