CheckBox On A Detail WinForm?
Sep 25, 2009
The application is written using VB in VS 2008 with .NET 3.5 I have a table in SQL Server that represents Invoices and in the table is a field named "Paid" which is define as CHAR 1 with values of "Y" or "N". Nulls are not allowed.I have two Bound Windows forms to manage the Invoice data, one with a DataGridView and the other a Detail Form. Both use the CheckBox control for the Paid field.
In the DataGridView I can define values for the TrueValue and FalseValue and the Database is updated correctly.I can not find anything like this for the CheckBox control on the detail form.Am I missing something? It seems like if it is one it would be in the other for the same control.handle a CheckBox on a Detail form? CheckedChanged?, NewClass for the CheckBox (which I have not done before)? Other?

There are a lot of master/detail databinding examples with detail form on the same window than the master, I can't find any example where detail is in a new window.

How do you disable additional checkbox selections/deselections without sacrificing the functionality of the ListView? I know you can call: ListView.Enabled = False, but that also disables any scrolling within it.
For example: I have a timer that starts a backup based on the Listview items that are checked. After a certain time, I don't want the end-user to be able to click on any of the checkboxes within the listview (so I have a set number of items to backup), but I do want them to be able to scroll the list while the backup is being performed. I tried this[code]...

I use a simple master-detail form using Visual basic 2005 express edition and ms sql server 2005 express edition, as well.
The master table is dept (deptno int, dname nvarchar(50)) .
The deail table is emp (empno int, deptno int, ename nvarchar(50)).
The primary key for the dept table is deptno and for the emp table is empno.
There is also a foreign key (deptno on emp table).
I created a new project, connected to a db (called test.mdf) and created a data source consisting the two of the above reffered tables.
I dragged and dropped these tables on the form and i noticed the following:
1)When the form opens... the system queries the database and displays the data on each block on the form.
2)I insert and/or update a record on the master table (dept) and everything goes well...
3)I try to insert and/or update a record on the detail table (emp) and nothing is changed on the detail table - without any error.
4)When i try to insert and/or update a record on the detail table (emp) which violates the primary key constraint or foreign key the system complaints...(as expected).

I have made several posts on here lately regarding master/detail or parent/child data setups but no one has been able to help. It seems like a subject people don't like to tackle BUT I really need help.
I'm having a real hard with the DataView.RowFilter functionality and it is driving me insane.
For the most part, I have the basic master/detail functionality working. When you select a record in the first grid, it shows the correct data in the second grid. When you enter a record in the first grid, you can enter related data in the second grid. I accomplish this by using a dataview and row filter bound to the 2nd grid. When you change the record in the first grid, the rowfilter for the 2nd grid is restated and reapplied.
The problem arises when I overwrite the primary field value in the first grid and the detail records become orphaned. You would think all I have to do is change the ID in the 2nd grid to match the new ID in the 1st grid but this is where I am having problems. I wrote a loop to change the ID of each record currently loaded in the 2nd grid to match the newly changed ID in the first grid. The code is here:
Code:
Dim I As Integer
For I = AuthorizationGroupsDGV.Rows.Count - 2 To 0 Step -1
AuthorizationGroupsDGV.Rows(I).Cells(0).Value = StrEmployeeID
Next
I have used this code before and it works great. It has to step backwards through the grid because when the ID's are changed, they no longer match the RowFilter criteria and they disappear from the grid. They still exist in the dataset. The problem is, while the code "works" the intended effect does not. Some of the records completely disappear from the dataset and do not reload when I restate the row filter against the new ID number.

I have a dataset containing 2 tables,Customers and Contacts. Just showing the master-detail is not a problem. Problem occurs when I try to search the master table to bring in the detail table. Searching the master table shows only the master record, but not the related detail records. Adding a 'findby' query on the detail table only shows the records.url.. Normally when the master table is filled, the detail record shows in a form.

I have some DataGridView code written in vb.net. (Nothing is attached to a datasource.)The 4th column is a checkbox cell.How do I detect if that checkBox is checked or unchecked?This code strangely reports TRUE or FALSE at random times. It even turns ON the checkbox in rows other than the row I clicked in. (Huh?)
Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
Dim whichGrid As DataGridView = CType(sender, DataGridView)

I've tried countless other methods... none seem to actually get the checkbox ON/OFF value in vb.net.

I've got a form with parent-child setup. The parent displays name and other demographic info.The child displays multiple addresses, one row at a time. There can only be one primary address for a name and this is designated by a checkbox at the top of the child form.If the user wants to change the primary address to another address,then they find the other address and click on the checkbox.The form checks the other addresses and if one is found that is designated as primary,the user is warned that one already exists and prompts them to change it.
So for example, a name has 2 addresses, the 2nd being the primary address.The user wants to change the 1st address to be primary.They click on the Primary Address checkbox for the 1st address.A warning displays that there is already an address listed as primary.The user then answers the prompt to change the 1st address to the primary address.The checkbox for the 2nd address will be unchecked and the checkbox will be checked for the 1st address.My problem is getting the checkbox unchecked for the 2nd address.If I close the form and reopen, then the checkbox is unchecked.How do I refresh the checkbox for the 2nd address?Here is the code I'm using to find if an address has already been marked as primary:[code]......

Is there a way to configure the debugger or write code in such a way as to get more information when first chance exceptions happen? I understand they are generally not harmful and I do quite a bit of exception handling in code but when I'm doing database operations it's to know when first chance exceptions occur. Of course I can see them in the Immediate Window in VS but I would like a full stack trace, not ust a line saying "A first chance exception..."

Say I have a class that stores a value, and raises events when that value is changed:
[code]...
also say that I have a container class which contains a number of objects of this style, and raises its own event when any contained object changes its value:
[code]...
Given this setup, what is the best way to expose the stored variables in the StoreEventMonitors class? As three integers As three RaiseEventWhenStoredValueChanges objects?there is a good reason to use three different event-raising Objects, instead of simply writing a new class which stores three integers.

I have created data sources from my objects in my project, some of which have other objects as members. When I want to bind a some objects to a data grid I would like to display some of the values from the member objects in the data grid as well but the examples I have come across seem to use an entire other datagrid or controls to display these member object values.

In my app I have a main form listing basic customer info in a datagridview. When the user single-clicks a customer, I want all the customers info to appear on the right side of the main form for viewing/editing/deleting, etc. Also, if the user double-clicks a customer I want a new form to appear (not an MDI child, but an external form) to appear with the same info for viewing/editing/deleting, etc. (Kind of like MS Outlook where you can open an item in the main Outlook window or externally).Since the external form and the right side of the main form need to show the same info and have the same functionality, I created a User Control to house all the customers detail controls and the ability to edit or delete.
Questions: Is using a User Control the best way to go?
The customer data on the main form is brought in via dataset, tableadapter and bindingsource. When a user single or double clicks a customer, that customers ID needs to get to the details User Control, regardless of whether it's in the main form or external form. What's the best way to get that customer ID to the User Control? Or should the main form "pass" the data binding source to the User Control?Once the customer ID has been received in the User Control, what's the best way to show that customer's details and prepare it for editing?
