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.

Forms Data Controls :: Dynamically Created Checkbox In GridView Are Lost In The Postback?

Mar 3, 2010

In design time I created a Gridview and a delete button in a page test.aspx:


The program stopped at statement "if ((row.Cells[COL_INDEX_SELECTED].Controls[0] as CheckBox).Checked)",

because it cannot find the checkbox created before.

I tried to shift all the code in Page_Load to Page_Init, but the ticked checkboxes are still lost.

I could find the ticked checkboxes names in its request object parameters(this.Request.Params.AllKey) if I setup a breakpoint on the error statement.

Does anyone konw what's happening and how to retrieve the selected rows?

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 Im 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.

A piece of my code:

Web Forms :: Attaching A Dynamically Created Checkbox To The Server Side Form?

Jul 29, 2010

I am trying to allow for multiple selection check boxes that are created dynamically.

The Following code is written for each row in the dataTable (I print it as HTML code)

<input type='checkbox' name='multiCheck' id='chk{1}' value='{1}' runat='server'/>

however, on the server side (after postback) I can't read them from the Request Object. How do I "mark" them so I can read them at the postback?

protected void DeleteSelection_Click(object sender, ImageClickEventArgs e)
int multiIdsToDelete = Request.Form["multiCheck"]; <-- In the Future will be added to an array so I can do the delete for each row selected.

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.

Forms Data Controls :: Dynamic Gridview With Dropdownlist / Dynamically Set The List Values Based On Parameters (of The Row They Are On)

May 28, 2010

I'm new to web dev and c# so please bare with me. I am trying to create a dynamic gridview in a web form for users to to answer questions with (code below).

The dificulty im having is that i am nesting a dropdwonlist in the gridview and want to be able to dynamically set the list values based on parameters (of the row they are on). These values are in the main dataset for the gridview as each row represents a questionid and question text and then a ddl for the criteria...

I just don't know how to set the values for the dropdown all the code so far is below... just need to be able to populate the dropdowns with the relevant values.

I have created a stored proc to return the different criteria based on the questionid and questionGroupid which is the dataset that populates the other fields in the gridview: dbo.usp_QuestionCriteria @QuestionGroupId, @QuestionId

I have added this as a tableadapter called criteriaTableAdapter in a xsd file as well using the wizard... not sure if this is the right option though or just use the same method as i have for the other stored procedure as in the code below:

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 ).
