Web Forms :: Add Event Handler To Dynamically Created Button?

Oct 5, 2010

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:

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 :: Programmatically Created Event Handler For A Button Doesn't Fire Up?

Mar 21, 2010

I'm trying to manually create a button and add a Click event handler for it in code. However when the button is clicked the event handler doesn't seem to react on event (or event isn't called).

we tested the code in Visual Studio 2008 and everything worked just as it should. And I'm using Visual Web Developer 2005 XE. So I assume that I'm missing something to be done manually being in VWD 2005 XE, or the problem is in VWD 2005 XE it self.

here is what I'm doing:

VS 2010 - Event Handler For A Button Created Programmatically

Jan 25, 2012

I need to generate a button way after the page loads but I can't work out how to deal with the Event handler. If I do this when the page loads as shown bellow it works as intended but if I use the exact same method in a button it fails. (it creates the button but when I click the button it just disappears instead of showing a msgbox."I know I shouldn't use Msgbox in a web form but I only do it as a test then remove it"

Code:
Partial Class Default3
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim mybutton As Button
mybutton = New Button
mybutton.Text = "Submit"

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:

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 ?

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();
}

C# - How To Attach An Event Handler To Control Created At Runtime

Nov 10, 2010

I have a question connected with controls and event handling. Lets say I want to create a LinkButton.

protected void loadLinkButton()
{
ContentPlaceHolder content = (ContentPlaceHolder)this.Master.FindControl("MainContent");
LinkButton lnk = new LinkButton();
lnk.ID = "lnikBtn";
lnk.Text = "LinkButton";
lnk.Click += new System.EventHandler(lnk_Click);
content.Controls.Add(lnk);
}

Here is the event handler:

protected void lnk_Click(object sender, EventArgs e)
{
Label1.Text = "ok!";
}

If I run the loadLinkButton function inside Page_Load everything is ok. But when I try to run the loadLinkButton by clicking simple button, link button is created but event is not handled.

protected void Button1_Click(object sender, EventArgs e)
{
loadLinkButton();
}

I there any way to solve it? Or loadLinkButton must always regenerated on Page_Load, Page_init etc.

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 :: 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 :: 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.
