Access Objects On A Dynamically Created UserControl An A Dynamically Created Tab Page?
Dec 5, 2011I can usually find the answers to most of my questions via the Google Gods, but not this time.I have a form that has a TabPageControl and on that page a collection of labels and text boxes via a usercontrol.
On the form I have a button that allows the user to create a new tabpage, when the code adds a new page, it automatically adds the UserControl collection. I can't get my head around how to access the objects on the newly created tabpage.
What I need to be able todo is take the index of the tabpage that has focus and translate that against the UerContol name, but I havn't a clue how to do it!

Unable To Access The Dynamically Created Controls In Tabcontainer?
Jan 20, 2012I'm developing a chat system. In this I'm creating dynamic tab panels in a tab container when I change the selected index of the list box of users. In these tab panels I'm creating 2 text boxes and 1 button dynamically and adding a handler for the button click event. I'm storing the tabid's in the session state and recreating all the tabs in the page_init event. I can fire the button click event in the tab panel, in which I'm unable to access these dynamically created text boxes but I can access a label which I created statically. I used the findcontrol() method but it is showing an error message: "Use new command to create the textbox instances". It is showing something like I haven't created the instances of textbox.
View 1 RepliesAccess / Use Objects Created At Runtime
Dec 23, 2010I'm trying to develop a program that turns matrices into their reduced Echlon forms. The user specifies the number of Columns & Rows for the matrix, which is generated by the following Sub Routine
Private Sub ButCreate_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles ButCreate.Click
'Columns and Rows are specified by the user
rows = TxtRows.Text
columns = TxtColumns.Text
'clears all of the controls(text boxes) from the TableLayoutContainer
[Code] .....
How to do is access/manipulate those newly created textBoxes. After the user enters values to those boxes, I want to assign each of their columns to an array.
Access DB - Column Created At Runtime Is Not Updating?
Sep 19, 2011My program creates columns at runtime with the following code:
Cmd = New OleDb.OleDbCommand("ALTER TABLE [Parent] ADD [" & ColumnDate & "] int", con)
objCmd = New OleDb.OleDbCommand("ALTER TABLE [Parent] ADD [" & ColumnDate & "] int", con)
objCmd.ExecuteNonQuery()
I add data into the newly inserted column with the following code:
da.SelectCommand = New OleDb.OleDbCommand(sql, con)
Dim cb As New OleDb.OleDbCommandBuilder(da)
cb.QuotePrefix = "["
cb.QuoteSuffix = "]"
ds.Tables("SchoolMaticsDatabase").Rows(inc).Item(ColumnDate) = Hours * Num
da.Update(ds, "SchoolMaticsDatabase")
All of the above works fine; the issue arises when I try to edit the information originally placed in the newly added column. These are the approaches that I have taken. (None of them give an error message; it simply won't update within the database.)
da.SelectCommand = New OleDb.OleDbCommand(sql, con)
Dim cb As New OleDb.OleDbCommandBuilder(da)
cb.QuotePrefix = "["
[code]....
I added a column to the table manually via opening the access database and all the above approaches work for editing data stored in that column. So I believe it is something to do with the fact that the columns are created at run time.

Dynamically Creating Methods For Dynamically Created Buttons?
Mar 15, 2011I have this code.
Code:
Public Class Form1
Dim NPB As Button
Dim x As Integer
[code]....
As you can see, when I open a program from my menu, a new button will be created with text similar to this, "C:Program ". The button it self will not do anything. How can I create the method at the same time the button it is for is created? Also how can I change the text do that it gives me, for example, CCleaner.exe instead of the whole target path?

Accessing Dynamically Created Labels - ASP.NET?
Apr 28, 2009My current project involves displaying questions/answers from two different databases to be used to compare values and make judgements. The number of questions, choices, and answers is all variable. Thus I am attempting to create labels dynamically to show the information on the screen and create textboxes to leave comments. My problem is not knowing how to then access these lables, since I can't code in to use "label_comments" & (i) as it doesn't exist (at least, I can't get it to work).
First, my code for creating and displaying the information:
db_connection = New SqlConnection(ConfigurationSettings.AppSettings("ConnectionStringMerrill3"))
db_connection.Open()

Add Events For Dynamically Created Buttons?
Jan 14, 2010My process is as follows:I access a database table to determine what questions to ask (20-100 questions).Each question is display along with, possibly, a "done" button.My code to do this is as follows:
If datareader("Who_Second").ToString = lbl_Your_Position.Text Then
Dim b1 As New ImageButton
b1.ID = "btn_second" & datareader("QCC_Q_ID").ToString
[code]....
What I need to do for each button is strip out what the "QCC_Q_ID" is for that button and insert information into another table of the DB.My partial code for this is as follows:
Sub btn_done_clicked(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs)
Dim MyDate As Date
Dim QCC_Q_ID, Position As String
[code]....
Two problems:1. My sub is never being called, so I can only assume that my "addhandler" is not working.2. QCC_Q_ID = e.ToString.... That doesn't seem right - is it? What I need to do is get the name of the button (btn_second13) and get just the number out of that (13). Is there any easier way to keep track of that ID?

Asp.net Mvc 1 Validation Using Dynamically Created Controls
Aug 11, 2010Using ASP.Net MVC1 and am dynamically creating the html in a model that is then dropped into the view and rendered at run time.
My view is a single page that looks like this:
<%@ Page Language="VB" Inherits="System.Web.Mvc.ViewPage" %>
<%=(ViewData("Content"))%>
This dynamically created content is mostly dropdownlist boxes in the format of
<form method=post action="/questions/nextBatch">
<div id="text">What is your preferred drink?</div>
<select>
[Code]....
Is it is possible to perform validation on the dropdowns lists to ensure that a value has been selected? If any of the dropdownlists that still have the default value (the "please make a selection" text) the page is then redisplayed with the font colour of the question or dropdownlist box changed to say red?
I'm from the Webforms world and have made the switch over to MVC (which I really like!) and I know there are some pretty slick validation tools out there but you seem to have to account for them within the view itself.
I cannot pass a HTML helper through the viewdata of the controller as it does not render unless it has been coded directly into the view itself.
Also, I'm looking for a pure asp.net solution as I cannot use javascript due to accessiblity concerns. I can access all the values of the dropdowns without any problems throug the formscollection object but from there I'm a bit stuck.

Close Dynamically Created Form
Dec 8, 2008I have a form which when button1 is pressed creates and displays a new form. From this form a user has the choice yes or no buttons. Each button has its own handler and script it executes. If yes is clicked i want to run the script and then close both forms. I used me.close() and that only closes the orriginal form and leaves the dynamically created on open. If I place a call to form2.close() in the yes handler sub I get an error that it is not declared. How can i close this second form?
