Web Forms :: Handling Dynamically Created Tables And Autopostback Controls?

Jun 17, 2010

I just can't wrap my head over this and don't have enough time to read long articles.

I already have an HTM Table on my form. I dynamically create New Roows and Cells and keep adding them to the Table .

The cells Contain Labels, Textboxes, Drop downs and Buttons. I also add Handlers to the dropdowns

The form loads perfectly the first time. But when I change the value in a drop down, on the postback, I get a msg saying that " There are multiple controls with the same name 'txtCheckin' . How do I handle this?

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.

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 :: Want To Put Code In Dynamically Created Controls?

May 28, 2010

I need to create web controls (e.g. label etc) dynamically.The problem is that for example,

on my onload event, I create a label. The text of the label is read from one line of a xml file.

But sometimes the text should be like " Messages (4)", in which the message count is something not generic and need some logic to calculate. I tried to put things like "Message (<#% MessageCount %>) " in my xml file, but the displayed text label is:

Message (<#% MessageCount %>) instead of Message (4 ).

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.

Web Forms :: Maintaining Attributes Of Dynamically Created Controls?

Mar 1, 2011

have some code which dynamically generates a number of drop down lists to provide the user with different options. The items in these drop downlists contain a value which is a unique id for that particular combination of options and a text component which just plain text but not neccessarily unique. I then have assigned a handler to these dropdownlists which is called on selected index changed to perform the relevant actions based on what options are selected. The problem is to make the system perform the correct action I need the unique ID from selectedValue of the drop down box but when it posts back it appears the selectedValue has been replaced to match the text of the item.

Dim dynDdl = New DropDownList()
dynDdl.ID = "ddlOpts" & i
dynDdl.AutoPostBack = True
AddHandler dynDdl.SelectedIndexChanged, AddressOf dynDdl_selectedIndexChanged

Forms Data Controls :: Dynamically Created Repeater Control

Dec 1, 2010

What I am trying to achieve:I am trying to take the value of the selected index and depending on what this value is (e.g. the case selection in the code below) run a different query on the dataset and then create a repeater control dynamically to output each row with an item template
that I can use css to style.

In other words: When a user choses a list item it shows only rows from the dataset that match the list item chosen. For example if a user choses Closed Tickets they only see rows from the dataset that have a STATUS of 'CLOSED'.

What I have done so far: [Code]....

What I'm struggling with at the moment is:

1) That the case selection works but the selection of the appropriate data from the dataset doesn't seem to be happening. And this data isn't getting stored in rows as I had hoped.

2) I'm not sure entirely how to display the dynamically created repeater control in the admin.aspx page.

Forms Data Controls :: Add Value In A Dynamically Created Dropdown List?

Jan 11, 2010

I have a database with some data in. Now I'm trying to show that data on my page whit a ListView.

For each object from the database a ListView will generate a dropdownlist.

I also have a DataPager on my page and this is where the problem occurs.

Each object generated from the database has a field that may look like this example.: 1,2,3.

In my code now I´m trying to split this string of comma character and add new items to my dropdownlist.

This works as long as I do not have DataPager on. But if I choose to view an x number of pages at the time when the page loads, I have value in the dropdownlists, only on my first page.
