Delete Dynamically Created Labels On Postback In Asp.net?
Jul 6, 2011
I have a form that has an array of dynamically created labels of varying size based on a search from a database. The problem I'm having is that when the user searches for a different term, it looks like some of the labels don't get new values. Here's my code for adding the labels:
If rdr.HasRows Then
ReDim Preserve entities(cnt)
While rdr.Read()
[Code].....
I've tried for loop over the controls in panel1 to dispose of any still on there in both the page_load and page_init subs, but neither had an effect. I don't know if it might have something to do with controls having the same IDs after the postback.

I have a page that contains some dynamically created controls (TextBox and DropDownList). When a postback occurs, the TextBoxes keep their values, but the DropDownLists lose their ListItems. This is quite confusing, since the page level DropDownList also keeps its ListItems.
<%@ Page Language="VB"%>
<script runat="server">
Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs)

user control, I'm dynamically creating an arrary of several labels within a groupbox on the controls form. This is done in the load event.The user control is then placed on the form of mainapplication and then run. My problem being that the labels are invisiblen I launch the app. The visible property for the labels is set to true during the creation of the controls.

My 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()

I'm creating a series of labels at run time based on an array of strings made earlier in the program, but when i run, the labels aren't showing. The program is form based and the co-ordinates for the new labels are well within the bounds of the formHere's the code I'm using:
For i = 0 To 10
Dim lbl As Label
lbl = New Label

I have made a program wherein you the labels are dynamically created with a press of a button. if you press on the label, the label would then change color from white to blue. my problem is that how will you make the backcolor of the label change when the button3 is pressed.
here are the codes. placed the whole thing since I dunno if you guys would understand what I mean.

PS here is the link to what my program looks like. link to my program . the button3 in the image is Reserve Seat.

ive got code like the code below that creates textboxes dynamically. I want to be able to click a button and delete all of these textboxes i make, however im not sure how to do this. When i tell the program to remove the TBIndex control it does not do anything. The only way i get it to work is if i put the command in the same sub as this code. This code runs in a loop by the way.
So if the loop runs one time and creates the TBIndex control and i have a line of code right after to remove the textbox, then it does not show up on my form. But if i put the command in to remove the textboxes somewhere else and run the code the loop runs abunch of times and creates all teh textboxes and the loop is complete, then the remove control part is called and nothing happens. I just need a way to clear all the textboxes off my form with like a button. I also tried painting over the textboxes with a big grey rectangle but that dindt work.
TBIndex.Width = 54
TBIndex.Height = 20
TBIndex.Visible = True

I 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!

I 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?

How do you get a specific nested control of dynamically created controls (i.e. the child of a dynamic control)? The FindControl() method does not work because it only deals with TopLevel dynamic controls I believe.

I have a drop down menu, and based on which item is selected, I call a web service and then dynamically create some text boxes.The first time I drop down the menu and select an item, it works perfectly, and the text boxes are created and populated dynamically. However, the next time I drop down the menu (after the first postback), and select something different..fter the second postback, the original values remain in the textboxes.

I'm trying to have a for each loop in which 5 labels should be created.Each time the loop restarts the 5 labels should appear in a tabpage.The problem is, it only makes a label once, then it keeps on mving the label to a different tab instead of creating a new one for each tab.
It loops 5 times, thus filling 5 labels.Then the next 5 labels should get filled in a new tab.But it just moves the original labels. How do I force it to create a new label each time?

This may be simple, but im having a tough go at it. I'm trying to make a "review" section in a step through form, where the user can see everything that has been entered and if they choose go back and "edit" that information again. One section only has to show the information that has been added by the user, basically if they don't select a certain checkbox there is no reason to display the info for that box.I want to to dynamically create labels in a Panel (Panel7) on a TabPage (TabPage3), only for the checkbox information that was selected. This is what I have right now, and I am unable to see anything on the page, I have also tried without the panel and straight onto the tabpage itself to no avail.
MsgBox(CurPat, MsgBoxStyle.Critical)
If (CurPat = "True") Then
Dim lblTemp As New Label

I am creating an electronic display board using Visual Studio 2005, this will be an application using VB and not web based.What I am trying to do is use labels dynamicly and populate them from a dataset, Now there is a lot of labels on this board and to be honest the perfect solution would be to use a Data Grid View, unfortuantly I have to fit the information into a Custom Graphic that was created, hence the reason for labels.So obliviously I dont want to have to name each label and specify its information, for example:
Code:
Label1.text = MyDataSet.Tables(0).Rows(0).Item(0)
Label2.text = MyDataSet.Tables(0).Rows(1).Item(0)
Label3.text = MyDataSet.Tables(0).Rows(2).Item(0)
So I thought about something as follows but not sure how to get it work.Say I new I had 100 Labels Label1 to Label100.
Code:
Dim i as Integer
For i = 1 to 100
[code]....
Now the above doesnt work but it doesnt throw up any errors either.

I created a form with 2 labels 2 textboxes and a button. Basically it is a login from. When I launch the form it shows the blinking cursor in the 1st textbox(this is ok) but when i try to type nothing happens. Once i click the form(not the textbox-textbox works too but wanted to note it was the form) it works. I have tried doing textbox1.focus(). I have tried doing the form.focus(). Neither were successful. It may have nothing to do with focus but it seems to be that to me.

I'm currently making an application that involves time tables / scheduling. I'm required to generate a timetable for school teaching activities. in this application, I want to display the time slots using labels and I want to enable users to drag them around to place the subject cards in the available slots. I'm even confused with the control to use for the time slots. Right now I'm thinking of using datagridview for the time slot. So I'm trying to drag the labels around and placing them in the datagridview cells.
