Web Forms :: How To Get Dynamically Created LinkButton ID

Apr 25, 2013

I 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.

C# - How To Add An Onclick Event To A Dynamically Created Linkbutton

Feb 1, 2011

What I'm trying to accomplish is to set my dynamically created linkbutton with a onClick command so when click it will run a method in the code behind. This is my code:

protected void Page_Init(object sender, EventArgs e)
LoadLeftSide();
private void LoadLeftSide()

List<Post> list = PostHelper.GetAllPosts(filepath);

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 :: Use Dynamically Created Controls Such As A Checkbox List And Fill The Values Dynamically?

Sep 28, 2010

I'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, 2011

I 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.

Forms Data Controls :: Raise Click Event Of A Linkbutton Inside A Template Field That Was Created Programmatically

Jan 28, 2011

I need to generate a gridview with dynamic columns, on each cell I need a button that inserts-deletes a relationship in a database. The relationship is of course between what is represented by each column and row. I decided to use a gridview and create templatefields which I add programmatically to the table. I successfully got to that point but when i decided to raise a click event from the buttons or a rowcommand from the gridview I could not do it. Im looking into doing this with button fields right now but Im curious on how this can be accomplished?

Dynamically Add Linkbutton To Page Vb

Nov 27, 2010

I'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?

C# - Get The Sql Created By A Linq Query?

Jan 18, 2010

I've been developing a ASP.NET page and have been using LINQ to handle talking to MS SQL server. I'm ok at basic SQL, however I'm a lot better with designing queries using LINQ. I know they are similar but I find it easer to design complex queries in LINQ. My question is this: Is there a way to design a query in LINQ and then get the SQL that it generated? I would like to embed the SQL in a stored procedure since multiple pages (outside my control) will need to do the same query.
