Web Forms :: Event Handlers For Dynamically Built Controls?

Mar 22, 2010

reading on the forums about assigning event handlers to controls that are dynamically created via code and am just not getting anywhere.In my particular case, I'm rolling through a directory of images and creating ImageButton controls on the fly and want to assign the OnCommand event to a single handler.Then, by using the CommandName (which is different for each control) I can figure out which ImageButton was clicked and act accordingly.

The snippet below (which can be found in many posts on this topic) is inside a foreach which loops through the directory and gets each FileInfo (fi).Each is then added to a PlaceHolder (phImages).


This code compiles and runs but the event handler is never invoked when an ImageButton is clicked. I believe this is because you cannot, without some coding I'm not familiar enough to do yet, assign a handler to multiple controls.I say this because I ran into a similar problem in a Silverlight app I wrote and had to use a lambda (=>) operator to do something similar (although I admit to not knowing enough about this to know if this situation is the same).

Web Forms :: When To Wire Up Event Handlers For Dynamically Loaded User Controls

Jul 15, 2010

I have a situation where I dynamically load one of twenty user controls at a time in an ASP.net web page. Based on much reading I've done, I understand that I am to reload the user control upon postback via the Page_Init event handler. This I've done and it seems to work fine.

But now I would like to wire up assorted controls in the user controls such that when the value of each is changed, an event is fired and the web page is notified. Here's an example of how I'm doing that:

userControl.NewData_Handler += new EventHandler(UserControl_NewData_Handler);

There's a problem though. Because the user control is being done in Page_Init (ie. before Page_Load) I don't believe that a line of code such as the one above can function yet.

So I'm wondering what the best practice to do this is. It occurred to me that perhaps I could execute the line in the Page_Load event handler but I'm not sure if that's correct or not.

Web Forms :: ASP.NET Validation Controls Are Removing Client Event Handlers.

Nov 24, 2010

The textbox has an onblur event (the workings of the onblur event are irrelevant), and an associated RequiredFieldValidator. This code functions exactly as it should. However,if in the body onload event I simply raise an alert of the innerHTML of tr1 or td1, the onblur event does not appear (but it does work, and can be seen when I view source in IE7). If I remove the RequiredFieldValidator, the onblur event handler is shown in the alert, or if I retain the validator but change onblur to onfocus, then the event handler also appears in the alert. I need this to work as when the user increases the Quantity, duplicates of the table row are added (I have tried both cloneNode, and setting the innerHTML of each new table cell to that of the original, but as my alert proves, the onblur event handler is not included in what is copied). The same problem also occurs with onchange for select tags with validators. I am using Visual Studio 2008 (.Net
2), IE7 and IIS 7.

Forms Data Controls :: Adding Event Handlers To Formview Controls?

Dec 13, 2010

I've always understood that it was best practice to add event handlers in code in the page load event thus:

Button1.Attributes.Add("onclick", "alert('Hello');");
rather than "onclientclick=somefunction()"

My question is, how do you add event handlers to formview controls where the control(s) may only be on the edit template and not on the insert and read only templates.

Simply putting the code in the page load would produce an error.

Where should the statement be placed in such scenarios?

Web Forms :: Event Handlers Not Triggering Any Longer?

Sep 14, 2010

I've been working on a web form that has lost it's ability to respond to most event handlers, though code that I write in Page_Load still fires. No button click or text changed events will fire. This has been working for months, and suddenly stopped. I did a windiff comparison to an older version of the webform, and don't see anything suspicious.

DataSource Controls :: Enabling Paging On ObjectDataSource That Is Built Dynamically In Code Behind?

Oct 28, 2010

I have the following on my aspx page


Then in my code behind i have the following set up in 4+ button events, since each button serves a different purpose.. Prior to this past week, i was only working with 2 gridviews on the page.. that were linked to this datasource.. so everything was fine.. but recently had to add a Datalist to display the results a certain way.. I got it all working, but now that more records are in the table the datalist is growing in length on the page and cant figure out how to modify the current code to enable paging without having to redesign the logic all together to get it enabled.

Based on what i have below and above, is there a solution i can implement to implement paging ONLY for the Datalist? Or if it cant be specific, if enabled, will it affect the gridview that is already configured to enable paging, which already works?

Web Forms :: Can't Find Textbox Using FindControl In A Dynamically Built Table

I have an asp:table control that I construct dynamically. I place a few textboxes in it within a for loop and assign their IDs in code. I'll include an abbreviated code fragment showing how I'm doing this:


The page then displays correctly and the ID is set correctly when I view the source, but when I try to access the textbox later when the form is submitted the call to FindControl(idStr) returns null no matter what I do.

Web Forms :: Line Breaks In Dynamically Built Placeholder Control?

Feb 17, 2010

I have a Placeholder control on Employee Main Menu. Several SQL Data sources are run at page load in order to notify employees that something is due. Each "something is due" message is loaded into a unique label. Therefore the Placeholder could have several labels in them. For clarity's sake I'd like them separated by line breaks. However I understand from reading a previous forum item that "< /br>" are ignored. How can I embed a line break when PlaceHolder_Msg.Controls.Count > 1

AJAX :: Dynamically Built Accordion Controls / Keeping Only The Basic Empty Structure, And Re-build It All In A Single Post To The Server?

Apr 27, 2010

I have a dialogue window that contains an Accordion Control that is dynamically built. The only thing that appears on my source page is the opening and closing tags for the control. The panes and the controls that appear on the panes are all added dynamically based on records in a database.

Now here is my situation, if a certian action is performed on one of the controls then I want to save that controls data and make it no longer available for use, this was easily accomplished by having the control hide itself. An issue arises though when I have hidden all of the controls on a certain pane, the header for the pane still exists and this is not the desired result.

What I would like is to be able to dynamically remove the entire contents of the control and then re-build it. Due to the timing of the events in the page post back sequence, a simple call to the method that builds the control will not work and if an explanation is required I will provide one. Also, looping through all of the panes and the controls on each pane will not work since after the first pass through the loop the panes collection is mutated, the enum table for the control is no longer correct since the initial pane has been removed, as a result the for loop throws an error.

Can any one come up with a way that I can clear out the control, keeping only the basic empty structure, and re-build it all in a single post to the server?

Which Access Modifier For Event Handlers

Apr 1, 2010

I've been programming ASP.NET for a number of years and have got into the habit of using the public access modifier when writing event handlers for nested controls. e.g.

LinkButton ln = new LinkButton();
ln.Click += new EventHandler(LinkClick);
public void LinkClick(object sender, EventArgs e)

I think I started using public because I ran into errors when using other modifiers. Is this the correct one to use here? Does it depend whether you're writing a Page / UserControl / other?

I would like to have the shared/static event and delegate on the web control and then, maybe in Global.asax (if not possible elsewhere) handle that event.

How can I do this? It seems I cannot access objects from other pages/controls.

C# - Setting Class-Level Variable To Use Between Event Handlers?

Mar 17, 2010

I'm having a hard time understanding why the following code doesn't work. I'm sure it's something remedial that I'm missing or not understanding. I currently have a page that asks for user input. If, based on the input and logged in user, I find data from this page already in the database, I need to update the existing records rather than creating new ones, so I set a class-level bool to true. The problem is, when MyNextButton is clicked, PreviouslySubmitted is still false. So, I'm not sure how to make the value of this variable persist.

public partial class MyForm : System.Web.UI.Page
private bool PreviouslySubmitted;
protected void Page_Load(object sender, EventArgs e)
MyButton.Click +=
(o, i) =>
q = from a in db.TableA
where (a.SomeField == SomeValue)
select a;
PreviouslySubmitted = true;
//populate the form's fields with values from database for user to revise
MyNextButton.Click +=
(o, i) =>
//the value of PreviouslySubmitted is false at this point,
//even if I made sure it was set to true the previous postback
//update database
//insert into database
