Web Forms :: How To Get Dynamically Created LinkButton ID
Apr 25, 2013I have a link button let's say LB1 wherein on click of the LB1 a modalpopupextendar will open up with a textbox where we can enter the message and onclick of Ok button the entered message will be saved. Let's say we have repeated the above steps for thrice. So there will be three rows created in DB. Let's say column name UID is the primary key.Now, I am displaying the each message inside a panel along with Link Button(LB2) which is created dynamically while reading the text. So,The first row will contain
UID:1 Message:Message1
Comments:Comments Link Button(LB2)
The second row will contain
UID:2 Message:Message2
Comments:Comments Link Button(LB2)
The third row will contain
UID:3 Message:Message3
Comments:Comments Link Button(LB2)
When I click on Comments Link Button(LB2) a modalpopupextendar will popup wherein we can enter the comments. Let's say we are clicking on LinkButton of Message 1, a pop up opens and after entering comments and ok button the comments are saved for all the three messages instead of saving it for message 1, i.e I couldn't find the unique id of the message.

Web Forms :: Click Event Not Firing On Dynamically Created LinkButton
Jun 22, 2010I 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 :: Linkbutton In Dynamically Loaded User Control Does Not Handle Command Event
Feb 27, 2011I have a user control that is dynamically added to a placeholder control inside an update panel in my main page. The user control has a linkbutton where I try to handle its Command event. The first time the link button is clicked after the user control loads, the form posts back but the command event handler does not execute, although the user control is still on the screen. The second and subsequent times the link button is clicked it works perfectly. When the user control first loads and I mouse over the link button, the browser status bar says: javascript: __doPostBack('ctl08$lbTest',''). After the first click, when I mouseover the link button the browser status bar shows javascript:__doPostBack('ctl07$lbTest',''). Why the changed in id, I can't figure but it must be why it is not hitting the event handler the first time it's clicked. Here is the cs code that loads the user control:

Forms Data Controls :: Gridview With Links / How To Dynamically Add Linkbutton Columns From Code Behind
Jan 26, 2010I have been searching for some time on the net for guidance on this question. Finally thought I will ask here...
I have a gridview that needs to be generated from code behind. There is a column with a name field and the remaining columns give the different user-ids linked to that id. Like this:
-- NAME, ID1, ID2, ID3......
The Name column will be populated from a table that has the Name as well as number of ID's associated with that name. eg [Name1][3]
I need to display linkbuttons that link to user-id related documents in columns 2 to n for each name.How do I dynamically add linkbutton columns from code behind?
Forms Data Controls :: Dynamically Creating Gridview Template - Linkbutton Click Not Working?
Aug 25, 2010I have written some code to dynamically generate template columns for gridview which works well. However, each cell in the gridview has to be a linkbutton, which when clicked does a db update and redirects to a specific url with some parameters in it.
I have attached a click event handler to the linkbutton in the InstantiateIn method but the event does not seem to fire.

Dynamically Add Linkbutton To Page Vb
Nov 27, 2010I'm trying to programatically add some link buttons to a page.
I'm trying to follow an example that I've seen online but can't get it to work.
I want the linkbutton to call a sub e.g. download_file(,)
As an example what I have is:
Dim lb = New LinkButton()
lb.CausesValidation = True
lb.Attributes.Add("runat", "server")
lb.CommandName = "lb_Click"
lb.CommandArgument = "test"
lb.Text = reader("filename")
lb.EnableViewState = True
lb.Enabled = True
AddHandler lb.Click, AddressOf download_file
Panel1.Controls.Add(lb)
Getting the button(s) to appear would be a start! Also, do I need to put them on a panel?

AJAX :: Dynamically Added LinkButton Not Getting Href Rendered
Feb 19, 2010There seem to be about a zillion posts on similar situations, but I can't seem to find an answer in any of them. I've tried numerous techniques that I've seen, but nothing is making a difference. I have a Master page with an UpdatePanel with a ContentPlaceholder. In the content page I have a calendar. Above the calendar are LinkButtons that trigger a Command event to switch between Day Week and Month views. In the calendar DayRender event I am adding items to each day of the calendar. Items are pulled from a database. All items are contain within a dynamically generated div to help with layout. Each event that is added is a hyperlink that takes the user to a page where they can edit details of the event.
If there are more than 4 events, I'm adding a LinkButton with the text, "(more...)". I'd like that to trigger a Command event so that I can switch to the Day view of the appropriate day:
[Code]....
The problem is that, while the anchor tag gets generated with the proper text and ID, no href attribute is rendered and, as a result, nothing happens when you click "(more...)". I've tried switching to a Click event, but it does the same thing. (And I need the Command event to use the code I already have in place for some other buttons.) I've tried rendering it as an asp:Hyperlink and using ClientScript.GetPostBackClientHyperlink. That gives me a hyperlink, but I don't know how to get it to trigger so it results in the server interpreting it as a Command event and linking it to the proper event handler.

Data Controls :: Dynamically Add LinkButton Inside Nested (Child) GridView
May 7, 2015I am requested by my manager to develop a web page called staff deployment plan that will involve two GridViews, that is the Parent GridView and Child GridView. The Parent GridView will display two columns which are EmployeeNames and WorkingDays - the working days column is a heading of Child GridView and the child gridview displays columns as current working days for example: the month of November 2014 has 20 working days excluding weekends and public holidays in South Africa, so the columns for child gridview are like this:
3 Nov, 4 Nov, 6 Nov...etc
The problem that am experiencing now:
Is to add LinkButton for each column on the Child GridView and to create command event for each linkbutton inside a child gridview (remember this child gridview is inside a parent gridview) and the link button when is click it should display a popup window.
Dynamically Added Linkbutton Click Doesn't Fire (init Only) - Updatepanel And Triggers

My problem is that when I click on a linkbutton than the one selected, it doesn't highlight the selected linkbutton, because postback has been initialized. Instead it highlights the linkbutton that I have specified in the Page_Load event.

LinkButton's OnClick Does Not Fire In IE8 / Why Can't IE8 Accept Anything Within LinkButton
Oct 20, 2010The following works just fine in Chrome.
<asp:LinkButton runat="server" ID="lbEdit" OnClick="lbEdit_Click">
<button type="button" class="edit">
Edit
</button>
</asp:LinkButton>
And here is the CSS for button and its subclass.
[code]...
As you can see, nothing special; just colors and beautiful things.
I click on the blue Edit button and it fires the OnClick postback just fine.... in Chrome! But if I do the same in IE8, it just does nothing; doesn't even detect a click.
I removed the tag and kept just the word "Edit", and it works just fine in IE8 as a simple underlined link; the postback fires.
So, Why can't IE8 accept anything within LinkButton?

Web Forms :: Use Dynamically Created Controls Such As A Checkbox List And Fill The Values Dynamically?
Sep 28, 2010I'm creating an quiz application which queries the database and extracts the questions and choices. I use dynamically created controls such as a checkbox list and fill the values dynamically. How do I do this? Right now I have these functions:
array_random_init(); this creates a 10 element integer array from 1-20 - extract_question(i): this extracts a question indexed at i in DB, I created the controls and set the appropriate text in this function. - validate_question(i); this is called by button_click and validates the question i according to DB.
I understand I have to recreate the controls in Page_init on postback, but what should it look like? Do I need to add "if IsPostBack" in page_init, or do I create the controls in page_init() and reset their properties in page_load when I use extract_question(i)? Also, I cannot seem to clear the selected boxes on postback, I added page directive "enableviewstate=false" but it doesn't work.
Web Forms :: How To Use AddHandler To Dynamically Assign Events To Dynamically Created Buttons
Feb 14, 2011I have a website that sales associates access to view account information with clients. S.A's can only view information for accounts that they are tied to. Some clients have more than one account, S.A's can be tied to more than one account, but not all accounts of one client need to be tied to one S.A.
On the account info pages, I have account numbers (dynamically displayed labels) displayed of other accounts that the account client is associated with, which the S.A's can see. I'm modding this so that if the S.A has viewing permissions of any of the other accounts on that list of accounts, that instead of a label being displayed, a button directing them to that account page will display instead. In order for this to work, I have to attach a security function to the button, otherwise the page will blow out on the S.A's.
So I'm running a piece that is displaying a button instead of a label, which is working fine. My problem is when I try to attach the security event to the dynamically displayed buttons. It seems that the page just posts back and doesn't execute my code at all.
On my Page_Load, I'm running this after the buttons and labels are displayed:
For x = 0 to tblAccountList.Rows.Count - 1
'use a try to target the button, use catch to handle if it's instead a label, only one cell per row.
Try
Dim accountLink as Button = tblAccountList.Rows(x).Controls(0)
Addhandler accountLink.Click, AddressOf Me.PermissionViewCheck
Catch ex as InvalidCastException
Continue For
End Try
Next
I don't have any code checking for postbacks or anything like that, but the "PermissionViewCheck" event never fires and just reposts the page.
Web Forms :: How To Retrieve LinkButton Value
