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.
A Form is to Accept User Name and Password from user, after verification the form should display another form that will accept user's full data. When a user press the Ok button, the information entered on this form should be display in another form (Showing the user what he/she has entered)

NB: i am trying create an instance of the second form in the third form and declare a variable in the third form that will holed the value, but still not working I want to learn .NET Programming in VC#, ASP.NET And VB.NET. I am student and really get excited when it comes to programming
I have a question, I can't really find the answer...Basically I have 2 FormsIn form number 1 I have 2 pictureboxes. I want to create a checkbox in form2 that says if checkbox 1 is checked then show picture 1 in form 1
I have a ListView with Checkboxes in vb.net and what I want to do is when the user check the checkbox, the program ignore the response of the user in checking the checkbox, instead it leaves the checkbox uncheck.
I am creating an Interactive map which displays the facilities when the user clicks on the Checkbox, such as toilets.It will display all the toilet locations via PictureBoxes.I want to do this without having to write all this code?[code].....
i have 5 checkboxes in webform and textbox1... when i search the record using the date specified in textbox1 when i enter 11-Dec-2010 in Textbox1 and click on submit button then checkbox1, checkbox2, and checkbox3 will be disabled and unchecked .....
I have a DataGridViewCheckBoxColumn who's column name is "booReadyToReport want to hide all the checkboxes in this column if "bintAnalyteCodeID" doesn't equal the selected value in a combobox on my form. ut I run this bit of code the DataGridView DataError event fires currently, have nothing in the event except an comment. he code seems to work, but I'm new to VB.NET and I'm wondering if this is the correct way to handle thishould I use the CellPainting event?
highlight rows with RBF3 For Each dr As DataGridViewRow In Me.dgvCalculatedResults.Rows f dr.Cells("bintAnalyteCodeID").Value = Me.cbxAnalyte.SelectedValue Then
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)
[code].....
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]......
I have 2 columns of checkboxes in a gridview, where the header also contains a checkbox. If i select the header checkbox, it will check all corresponding checkboxes in its colomnow, what I want to happen is if I select column 1 checkbox, column 2 checkboxes should get unchecked and vice-versa.

I am refreshing a form, and I want to assure the checkboxes are cleared when refreshing. I can clear the textboxes and masked textboxes, but cannot figure out to revert the checkbox back to the UnChecked state.
I have a database with 2 tables master and detail, the detail has a picture field and the PK and FK. I use this code to navigate through the records, is there any simpliest way?
me.bindingcontext(dataset11,"Table1").position += 1 me.bindingcontext(dataset11,"scan").position = textbox1.text where scan the detail and textbox1.text the PK of the master, it is a little slow.
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..."
I am working on a project where I need display a list of items in a combobox and then display the details for each item in some textboxes.For example.I have a medications table,
ID (uniqueid), Name (varchar), Prescribed(bit), Usage(varchar), StartedTaking(datetime), HowTaken(varchar)
In the combobox I want to display the Name, and use the ID as the value. Then when an item is selected it will show the Prescribed, StartedTaking, HowTaken and Usage values in the textboxes.Heres the code i started writing..
Imports System Imports System.Drawing Imports System.Collections
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'm trying to add a new record in the DataSet in the master table. I'm not including a value in the unique ID field because it is added automatically by the server. At the moment I add second new row it throw me an error �Column 'ContactID' is constrained to be unique. Value '' is already present.� Do I need to set value of id column manually? How?
da.Fill(ds, "tblContactsProfil") daAddress.Fill(ds, "tblContactsProfilAddress") Dim relation As New DataRelation("ContactsDetail", _ ds.Tables("tblContactsProfil").Columns("ContactID"), _
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.
I have a listview set on 'Details' and its full of data. There's about 6-7 columns. I want to export certain rows if they are green and exclude the rest.
I have a table in which I populate a datagridview from. Now, I want to display certain info like Batchnumber in the first datagridview. And then in the second datagridview I want to display different data from the same table. Is it possible to have a master/detail scenario in this situation
I designed a form - please see a picture My first intend was to "link" each button on the menu [Employee Management, Contact Information,...] to different forms by coping this form and then designing the contents of the form using many repeated following code
2) Orders Table Contains fields -- Product Code , Product Name (These 2 fields Stores Product ID instade of Code and name.)
In my Orders Form, in datagridview I am showing actual Product Code and Product Name from Product Table using 2 datagridcomboboxcolumns by setting Display Member & Value Member Properties.But now I want to do If I select any Product Code from first combobox in datagriadview the other should display the Product Name of the selected product automatically. this can be in Master-Detail Form as well as normal single data form.Also, please tell me if it can be done in VB2008 Professional Edition.This we can do in Microsoft Access 97 & 2000. And it is very easy.Is it available in VB2008 like MS Access 97 & 2000.
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?
