Creating A Parent-Child Window Form In VB 2010?
Aug 4, 2011
I am trying to create a simple parent-child form in VB2010. I use a datagridview for each table/datasource and each is bound to the paretn/child table and each table grid fills correctly. What I want is the parent-child relation to enforce filling the child table with only rows that fulfill the current row on the parent. I have created a DataRelation in the form load, but it will not permit a relation between tables in 2 different datasets. If I attempt to place both tables in a single dataset and define the PK-FK relation in the SQL Serve,r I cannot create 2 separate datagrids from the same dataset.

I am looking to close the application when I click a cancel button in a login page, but I don't want to do it in such a way that Window 2 closes itself, but by sending some notification to Main Window, and Main Window closes the application. Here's the code that I have so far:
(in loginPage)
Public Event CloseApp As EventHandler
Private Sub CancelButton_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles CancelButton.Click

If I show a new non-modal child window using .Show(frmParent), and then the parent window is minimized, the child will get minimized automatically as well.

It has to be a simple line of code but I do not know how to construct it. Using VB 2010 Express, I have a MDI parent form and many child forms. I want the parent form to determine what child form is active and load data into the RichTextBox1 on the child form. Each Child form has a RichTextBox1. The parent form gets its data by loading a file.
I am close to a solution but just can't get there. You will see in the code below, if I make a direct reference to a specific child form, it works great. What I want to do is to use the Active Form function to determine which form to write to. I have looked at the MS tutorial which gets me close.

I have a parent form that has a list of items and each item has a unique ID. The user can open one or many of the items in a child form (it is set up in a tabbed MDI), but it can only open one instance of each item at a time.
In the parent form, I was going to make a collection (or something like that, maybe there is a better way) to keep track of which items are open in the child forms. I need to know when each child is closed so that it can be removed from the collection and reopened at a later time. I was thinking that when the child form closes, it somehow does something (like raise an event) that tells the parent form to remove the unique ID from the list of current open child forms.
My questions are, is this a good way to do this and I am pretty sure I would use the form closed event in the child form to update that parent form, but as well, I didn't know if this is the best way of handling it.
If raising the event is a good way, are some examples on how to do it out there? I found some for controls, but not while the form is closing/closed.

I'm working on a sdi-like WPF application with VB as the code behind. Basically, I have a main window that has some tabs and a button that opens (shows) another child window. I need that child window to refer back to the parent main window and automatically bring it in focus and have a specific tab selected (via a button on that child). The child window is a separate class file with its own xaml and VB code in my project.In the child I tried using
My.Windows.MainWindow.myTabControl.ItemSelected = My.Windows.MainWindow.tabIWantSelected
My.Windows.MainWindow.Focus()
but this does not appear to work as the main window in the background doesn't appear to be referenced in this way. I can use My.[bla bla].Show() - but that creates a whole new instance of the main window on top of the old one. Activate() doesn't work either since the main window is already activated.It seems like a simple task but am I forced to use something like SetForegroundWindow()?

Here's an example of what I mean: I have Microsoft Word open. I click 'Save As' to open the SaveFileDialog. When I try to click back into Word the SvaeFileDialog window flashes and it plays a beep noise. More importantly, it doesn't let the main program gain focus whilst it's open.

I am making an address book for my final project in school, and have a few questions. In my address book, there is a feature to add groups so you can sort your contacts. The problem is, the add group feature is in a different form, I tried calling a procedure from the parent form to refresh all data but it does not work.[code]

I am trying to size an MDI form to fit its 2 children perfectly within itself but when I use simple sizing it doesn't work - the MDI form always introduces scroll bars and the children seem to be too big for the parent. My three mDI form methods where this occurs is below.

Note: I am working with Visual Studio 2010 Professional. Note: There are a lot of MDI Child posts, but none (that I have found) that apply to my scenario... Scenario I have an MDI form with a UserControl docked at the top. The UserControl is for navigation and is ~50 pixels in height. When I show a child form with its WindowState property already set to 'Maximized', the child form shows maximized in the MDI parent, but behind the UserControl.

I have two forms. Form A and Form B. Form A has a datagrid that is populated from a SQL Database Table query. When a button is pressed Form B is launched that allows you to add a record to the database table. I need for the datagrid to be refreshed and show the newly added record when I close form B and go back to the parent.

Basically I have two forms - Form1 has a DataGrid on it (Infragistics) and in the double-click row event it creates an instance of the EditForm and passes along the UniqueId for editing. Once the user saves the changes (if they make changes) - I want the DataGrid on Form1 to refresh. Here is how I thought I could get this to work ... I create a public property called RefreshRequired as boolean. Before unloading the EditForm it sets this property to true. Then Unloads. This continues the code in Form1 (which showed the EditForm as modal) but RefreshRequired is still showing as False? Why isn't my EditForm able to set the property?

form1 has datagridview, when I click "add new", form2 appears(details view, allowing me to add new records into datagridview on form1). when I click "add new" again, form2 appears again, if I click x times, form2 will appear x times. How do I stop the add new button and all the functions on form1 from working until form2 is closed?

I have a date selector on mdi parent that updates a property when date is changed. When I open a child form, it grabs the property just fine. However if I change the date again after the child is open the date does not change on the child unless I close and reopen the form as expected. What would be the best way to automatically update all open child forms when the date is changed on the parent at anytime? running a timer to parse the date property is impractical.

I have two forms....Mainform is filled with controls that are databound to a datasource.....then I have a child form that is used to edit data from parent form.......the data that is displayed on the child form uses the Filter() method of the binding source to display data only for the customer selected......
The child form has the standard OK and CANCEL buttons set up as dialog result.......after I edit the content in child form, the changes are displayed on the child form correctly......but when closing the child form and going back to the parent form the changes dont appear there unless I restart the application.....I also tried adding the tableadapter.update/fill method in the 'OK' dialog result event handler and it still doesnt work......
How can I make the changes take effect on the parent form without restarting the application?
