My _PrefillWizard method actually works for all the controls on my page except for those which are dynamically populated. The CheckBoxLists are such because they are automatically generated based on selectable values in a table in my DB. I already have this control in my markup like so... how do I force this to load and be ready before running my other code?[code]...

The code below displays a thumbnail of each image in a specific server directory and when I click on the image it pops up a nice full sized picture. It works perfectly.
I would however, like to be able to delete an image. I first thought I could have a button at the bottom of the page with a checkbox next to each image, giving it a uniqueID as per the filename but as they are dynamically created I couldn't figure how to handle the Click Event on the button for a randomly named Checkbox ID. Then I tried adding a button next to each item and then tried an OnClick & OnServerClick to call a Sub but this didn't work either.

I have a CheckBoxList where one of the options includes a textbox to fill in your own value. So I need to have that textbox become enabled when its checkbox (a ListItem in the CheckBoxList) is checked.This is the code behind, I'm not sure what to put in my If statement to test if that certain ListItem is checked.

I have a checkboxlist that is filled with items from an array. I want the user to be able to select the items they want to remove then press a button and have the items be removed from the array. I have never worked with a checkboxlist before so I'm not really sure how to go about this. Here is what I have tried so far:
[Code]...
When I re-display the array into the checkboxlist it shows that nothing was removed from the array.
I want to be able to show on the form1, the count of the number of items selected in a list. So if I tick one the number goes up, if I tick it down, the number goes down.
Checkboxlist is lstTAGs
Do I have to create a function, which counts each selected item every time I click on an item?
I have a checkboxlist which gets the data from XML file. If a user selects an item on checkboxlist, i just want to show that item and hide everything else. And beneath that, I want to add clickable text to let the use to choose something else. So if the use click on that text, the user will see the checkboxlist again with the first item selected.
Basically look like this. So how do we achieve this?

The menu strip should be created in the Form_Load event handler. I have to use a TextBox for user input. If the user enters information into the TextBox and clicks on the Add Button, the text should be added to a ComboBox control.A Menu should then be created that must be added to the menu strip dynamically.

is there a way i can add list item to this list dynamically in asp.net i am using vb
I want to create a combobox like winform control in VB.Net that makes suggestions dynamically; exactly as the address bar does in Google Chrome or IE 8/9. Basically on each keypress, get a list of items that match the entered text on a background thread(s) and show these items in the dropdown list as they are (possibly slowly) returned - either from DB queries, web services etc.
I have tried a couple of ideas, changing the AutoComplete list dynamically or binding to a list, which I then update. But I am getting some rather odd and incorrect results even when updating the list directly (on the main thread). I also tried implementing my own textbox control that shows a ListBox control where the dropdown would appear - this seemed a lot more reliable but I cannot get it to draw over the edge of forms etc when shown, as the combobox drop-down does.
I am currently using VB 2008 and there is a form I'm using which contains a listview control. I am dynamically filling the listview with groups and items. After I fill it up, it is supposed to look like this:
[CODE]...
Each item is specific for each group. The problem I have is that when I maximize the form to full size, and everything expands, the items change positions into something like this:
[CODE]...
How can I make the listview keep the items in the "row" view always, instead of the "column" view whether I maximize or not?
I am trying to create a basic quoting tool but got stuck on how to clear and change the item collection from within a combobox for a datagrid.What we have is a list of 4 columns like a. Device b.TypeofService c.State d.Price Inside a sql database. Data is also structure like above as well.
I have a datagridview where the user will populate a,b,c and the price will be display and a total at the end. However a,b, and c aren't related in my current application. The combobox will show all possible dinstinct values for each column.
This works fine but I want to refine the application to only show the values of b. which are in the database after the user select the value for a. I have tried searching on how to do this as I assume to the Contry/State/City situation but could not find anything for a datagridview control in VB.NET.
Can anyone point me in the right direction? If I cannot do this dynamically from within a datagridview I was thinking of maybe creating three combo box outside and having it populating the datagridview afterwards but it wouldn't be as nice.
How can you add a click event to dynamically created menu item?I thought I could do something like
