I've been programming for a while now and I have a Datagridview which is databound. It pulls up a list of my line items and that works fine. So I have:
OrderID, OrderType, OrderNumber, OrderDescription
Anyhow... these fields all come from the OrderDetails table. I have another table, AllOrders, where one OrderID can have multiple OrderNumbers.
What I need to do is:
1.) The OrderNumber column should be a dropdown list of all OrderNumbers from the AllOrders table where the OrderID matches.
2.) This column should also let users manually type in a value and it saves it to the list.
3.) When the user clicks a save button on the form I need to be able to reference the values from each row to save the selected value to the OrderDetails table.
I thought this would be something rather simple... and I've been pulling my hair out for days. Sometimes I can get the dropdown to load the OrderNumbers correctly, but I can't add one. I can get a ComboBox cell where I can add a value to the list, but I can't load the existing OrderNumbers, etc.

I have a Windows Forms DataGrid currently filled with text.What I want to do is have a ComboBox appear in a cell when the user enters it.After the user has chosen their item from the ComboBox list I want the ComboBox to be removed leaving just their selection as text in the DataGrid, when they leave the cell.

In previous versions (VB.NET 2003) I would do
datagrid.datasource = dataset.tables(0)
datagrid.datamember = "Column1" 'Where this is the name of the column
This would show me just that column in the grid regardless of the number of columns in the dataset.
In VB.NET 2008 I do: datagridview1.datasource = dataset.tables(0)
I see all the columns.I then add:
datagridview1.datamember = "Column1" 'Where Column1 is the column name
I then have an empty grid.How does one get only a single column to show in the grid from a multi-column data source? I am using internal code to populate the datasets and tables.

As part of a user interface I'm designing, I'd like the user to encounter the following: when the user wants to edit a value in a cell, the cell in the DataGridView is replaced by a DataGridViewComboBoxCell. This is working now, however, when the user enters the cell (edit cell) the edit cursor stays there, and the combobox won't show. When the user leaves the cell, the Combobox shows, and after again entering the cell and clicking on the combobox, the dropdown finally shows. So 6 clicks are necessary, and I'd like to reduce this to a maximum of two clicks.
Using VB.Net on Visual Studio 2008, with .net 3.5
This is my code:
Public Class Functions:
Public Sub ComboBox(ByVal source As System.Windows.Forms.BindingSource, ByVal MainView As System.Windows.Forms.DataGridView, ByVal valuemember As String, ByVal displaymember As String, ByVal row As Integer, ByVal column As Integer)

I am using vb.net 2010 and winforms and DataGridView. The DataGridView has a DataGridViewComboBox column. When I show the form with the DGV it shows this and empty grid but the column that contains the ComboBox shows the first item on the dropdown list. How can I have the ComboBox display nothing until it is clicked on and selected?

I am trying to make a list, separated by a comma, of entries from a single column in a SQL database. I have been spending the last several days searching for a way to do this, but every thing I found either didn't work, or wasn't exactly what I was looking for.
The query will pull all the email address that are not null. What I need to know is how to take the result of that query and make it look like this:
email0@address.com, email1@address.com, email2@address.com, etc, etc, ...
I feel like I should know this, but for the life of me, I can't remember nor can I find it in any of the textbooks I have.
I am using Visual Basic 2010 and SQL Server 2005. I also have access to Visual Basic 2005 if needed.

It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?
Private Sub DataGridView1_ColumnHeaderMouseClick(sender As Object, e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DataGridView1.ColumnHeaderMouseClick

I am working on DataEntry Forms in VB.NET There are two controls are having in a present window. One is Combobox and one is Textbox. Combobox values are Mobile, FAX, E-mail. By the mistake some one enter the values like , In the combobox-E-mail and in the Textbox-9987453434. Finally these are saved on the Database. But i want to Re Enter the values.
For this i was selected in the Combobox-Mobile and in the Textbox-9987453434. These are the right values i want to save on the database.
But here the problem is that Phone number column(Textbox) is Indexed. (Unique) or No Duplicates in the database. Now i want to update only one column which is coming from Combobox in the database.

Dim Comp = From C In db.Table1 _
Select C.Completed, C.Taken, C.Namne
Datagridview1.DataSource = Comp
Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values.
I want to display Completed and Taken as Checkbox columns (either ticked for True or un-ticked for false) but ofcourse i can't do this in EditColumn dialogue because the Datagridview is unbound.
how can i change this in code at runtime

How you might construct an array like the following: one column or entry would be a single integer, like 0, 1, 2, 3, 4... - i need this as an index of each one's position in the list the second would be 0 or 1, or true or false the third would itself be a list of integers 0,4,5,2,7,2,5,2...
So all together one entry would be {0; 0; 0,4,5,2,7,2,5,2} while the next might be {1; 0; 6,8,2,5,2,3}
I'm having a terrible time wrapping my head around this. It's mostly the third column which is actually a list in itself, that is giving me trouble

I have a gridview that is bound to a datasource on a Windows Form (VB.NET). The grid displays a list of "certifications", and each "certification" can be associated with many languages. So in the grid, I'd like to display "languages" as a column, and display a comma delimited list of the language names for each "certification".
In the "certification" class, one of the properties is a list of "language" objects, and each "language" has an ID (guid), name (string), and value (integer).
So in the datasource, I have the list of "languages", but I can't figure out how to display them in a column on the grid. The gridview won't let me add the language list property as a column.
So is the ONLY way to add a new property on the "certification" class, which returns a string that contains the comma delimited list, and show THAT on the grid? Or is there a way to display that list of "languages"?
