I have a troubling task. I have a page contained within an outer frame, on the outer frame is a user control which i need to populate with some data from within the containing page. The problem is the outer frame is rendered before i can get hold of the required data.
View 2 RepliesI am trying to populate a a listview control with items and subitems that a user enters into a group of textboxes on a form. It looks as if some of the code to do this has changed since VB6 and I am confused again. Here is the current code I am using without success:
lvSurgProcedure is the name of my listview control
Private Sub btnAddSurgeProcedure(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddSurgProcedure.Click
Dim lvItem As New ListViewItem

Does anyone know of a good way to have a user enter an amount of time (hours and minutes) using winforms controls? At the moment I have two numeric up downs, one for time and one for minutes that I then parse to create a timespan. The only other idea I have is a text box that a user can enter a "00:00" time in, and validate the input. Both of these ways seem a bit bad (in UI terms) though.

View 2 RepliesI want the background of my form to be the same color as the window frame color that the user selects, even if that changes. I selected System->WindowFrame as my background color, but it always remains a dark grey, regardless of what I have my window color set to. How else would I achieve what I want? I assumed I was doing it the correct way. Do I actually need code that gets the system window color and then apply it?
View 4 RepliesI have an aspx page that has two different user controls. I want to find user control A and be able to set properties, etc., from user control B.
I was thinking I could do something like this:
Dim CMFilters As Control = Me.Parent.FindControl("CMFilters")
...but that doesnt work to be able to set properties and call methods. I somehow need to get the user control and and declare it as that user control type.
In a user control I have the code shown below.
I now realize that it is incorrect because the container's InitializeComponent property initializations have not run yet and they must be run prior to Refresh being called.
How (where) can I run Refreash after the container has initialized this user control.[cod]e...

I want to populate a Combo Box with a list of names and from that have the contact information (address, phone, email, ect..) populate a series of textboxes. The list is roughly 20 names, but it could grow to a hundred or more. Since the contact information changes periodically, I would like a very easy way to maintain it (Excel or Access).
Update: I am just trying to understand whether I should use Linq (have to learn it) or is there some other way this should be done.
These are all databound to a Access table All of the binding is done with the data wizard so there are the standard bindingsource, table adapters, binding navigators, etc.On the binding navigator bar there are the standard "+" and "X" buttons to add and delete records. There is also the SAVE button.In my application, I want the user to press the "+" button to add a new record. When that happens, I want a few fields on the form to be prepopulated. Once the fields are prepopulated, then the user can continue making changes as needed before pressing the SAVE button. Now you might be quick to suggest the following - in the BindingNavigatorAddNewItem_Click event, add some line like this:

I have a listview with checkboxes on the left side and 2 columns of data. What I want to do is populate a listbox when the user checks a row in the listview. I've tried code in the Item_Check event. It does not pick up the item checked. It's as though it's behind. For example if my listview has a list of country codes and I check US, the code returns nothing but if I check another item, it picks up US. Same thing happens in the SelectedIndexChanged event. If I use a button, all works as expected.

I am very new to programming so sorry for the simple question, but I am at a lose. What the program needs to do is take a user defined starting and ending range, and then build a table based on that range. Inside the table each record will need to have two check boxes.
So for example the user enters in a starting of ABC01 and ending ABC03 and clicks the button the table is populated like this;

View 4 RepliesI am trying to build a tournament bracket application. In order to build the application efficiently I would like to make a user control "GameControl" that represents a game and give it attributes that represent the names of the competitors "TeamNameA" and "TeamNameB" ,an attribute "Winner" to represent which team should move on, and an attribute "NextRoundGame" that assigns another instance of the user control so that it can assign the "winner" to one of the "TeamName" attributes of the next round in the competition. If the controls were native to VB I feel like I could do it easily (I have only spent about 30 hours self teaching/tutorial following) but I can't seem to find out how to pass values to custom attributes of custom user controls through code.

View 1 RepliesI am using Visual Basic.Net 2003 with an Access 2000 database.
An integral part of the program that i'm working on is a DataGrid which I am filling from three different queries, based on the user's input. The Grid properties are coded with specific requirements for each of the queries. I have two simple (hopefully) problems.
1) There is no scroll bar on the grid and I can't find a property or event that will allow me to add the Vertical Scroll Bar. How do I do that.
2) The grids contain only four columns each. I want the user to be able to click on a cell and populate four string variables.
