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.
Dim accountLink as Button = tblAccountList.Rows(x).Controls(0)
Addhandler accountLink.Click, AddressOf Me.PermissionViewCheck
Catch ex as InvalidCastException
Continue For
End Try

I don't have any code checking for postbacks or anything like that, but the "PermissionViewCheck" event never fires and just reposts the page.

C# - Dynamically Update Attributes Of ASP Controls Dynamically?

Sep 2, 2010

In my aspx page, I have a number of drop down controls. I would like to update an attribute on each of the controls with "class=leftColumn" with the following line: propertyID.Attributes["nameOfAttribute"] = "false";
But instead of manually writing out each controlID and setting its attribute with the line above, I had hoped there was a way to go through and set the attribute on each control ID if it had class=leftcolumn. This is something I know is very easy with JQuery, BUT I need to do it with the code behind (C#) I was told this is not possible (i.e. to acquire a list of all the controls and then iterate through the list and give it the attribute or any other way. That manually setting each control like the above example is the only way in ASP.NET.

Cannot Find Selected Value Of Dynamically Added Controls In Repeater / How To Dynamically Add The Controls

Jan 11, 2011

I am creating a survey page that has a list of questions and answers that can be radiobuttonlists, checkboxlists or textboxes. These controls are added dynamically to a Repeater in its ItemDataBound event using Controls.Add.

I've managed to render the page ok but when I submit the form and iterate over the controls in the repeater to get the selectedvalues of the radiobuttons and textbox values, FindControl returns null. What do I need to do to get get the selected values? I've tried iterating over the RepeaterItems but that returned null too. I've tried different types of FindControl but it never resolves the control types.

It works if I add a declarative DataBinder in the Repeater like this

<asp:Repeater ID="rptSurvey" runat="server" Visible="true" EnableViewState="true" >
<%# DataBinder.Eval(Container.DataItem, "Question") %>

However, I want want to dynamically add the controls but in doing this i cant get the selectedvalues when submitting. This is tha main structure of my code...

Web Forms :: Dynamically Add More Fields

Sep 27, 2010

I have seen it on here or while googling, but never had a need for it with any projects, now i have a form that has 32 fields, PLUS up to 32 other possible fields.. Not sure how to go about this.. i dont think that having a form with 64 fields is the best solution as you may just need the first 32, but here is my attempt to explain it. I have a page which will gather configuration information, one of the things about this configuration is that you have a 1 to many relation with cameras.

So you have your set configuration for a location, but that location can have up to 32 possible cameras associated with it. But of course you may have just have one camara, so of course you would only need to add 1 new field. Any links to adding dynamic fields would be great.. the other thing is if fields are added dynamically, how to handle that in the insertign of the data into the database, since we wont know how many fields there will be until they hit the submit button.
