the datagridview seems more complicated the I thought it would be my problem is: how can I if I added three columns to my datagridview, let the program insert something with 2 variables and in the last column i would have to do some calculations with the column2 (like the sum of all rows in column2)

View 1 RepliesWith the DataGridView I'm used to just populate them with a list of some object, using the DataSource property. Now I want to just display properties from a single object, and I'm a bit confused on how to do it.. The object is updated through an API event, and I want to select some of the properties for displaying in the DataGridView, to look like this:.where "ValueX" is the name of the properties.Now, what would be my options for binding this to the DataGridView, such that property changes are automatically updated. Since an update also must invoke the control, does that mean I must reassign all bindings, or what logic is necessary in this case?
should I bind to an array, arrayList, stringList, dataTable etc? I guess I'm not sure which type of source will allow binding. Or if I should perhaps build the columns and cells of the grid and populate them "one-by-one" to the properties of the object?
we currently use our own 3rd party customer management system that is cloud-based. They offer pretty good reports; however, we need special reports and the only way to do this is to download our database though web services that the vendor offers. I have some education and experience with programming, but it has been a while. Instead of having to actively engage the webservices directly, our vendor has offered a stepping stone. They have a command line exe that interacts with the webservices and, with the use of different parameters, gets us to the point of having all the data downloaded in xml, csv, or screen printed - the only problem is that it will only do this a table at a time and there are 43 tables I need to interact with. I need to build something that can either be a console application or something that can be run automatically in the middle of the night when there is no load on the server.
Here is what I need to happen:
The command is CMSDownload.exe. It needs to login (again, there are already parameters set up to do this so I can hard code that into the script) Once logged in, the script needs to check a parameter that has been saved that signifies the last date of successful completion. (Obviously, it needs somewhere in the code to place this parameter also). As I mentioned before, each table needs to be downloaded into its own xml file individually. For instance, the following is one example of a table being downloaded in this fashion:
Generate an XML file of all of the data in the accounts table between '01/15/2009 09:13:34 AM' and 01/16/2009.CMSDownload -d somedn -u someusername -p somepassword -f c: empaccounts.xml -m xml -o all -t accounts -s 'start date' -e 'end date'
-d is a login component (credentials)
-u is a login component (username)

View 2 RepliesIn 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.

View 2 RepliesI have a single form with a datagridview on it showing values from an oracle database. I am trying to set up a way of detecting if the row/column I click on is empty or not, just as a little exercise. I have so far got this:
Private Sub DataGridView1_CellClick(ByVal sender As Object, _
ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) _
Handles DataGridView1.CellClick
Dim c, r As Integer
c = e.ColumnIndex
r = e.RowIndex
[Code] .....
The message going into lbl2 shows the co-ordinate values of any box I click in but as you can see with the IF statement below I am trying to see if the system can detect whenever I click in a value that is empty (null or ''). When I run my form and populate the list with a column of names I can click in 0, 0 cell and I get a message saying the 'Box is not empty' as above.
But when I click in any of the next boxes e.g. (1,0) (2,0) etc I get this:
'Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index'
Pointing to this line of
If Not DataGridView1.Item(r, c).Value Is Nothing Then
Not sure what this means at all. I am under the impression that my piece of code is gathering the value of the item depending on the co-ordinate values. so why should this fail? What index/collection is VB talking about?
I am using the DataGridView in Visual Basic 2008 Express with an Access 2000 database.
What I'm trying to do is allow the user to click on the Row Header and capture the contents of the 4 cells in the row to 4 dfined variables. I know that I can capture each cell individually by using the CellContentClick event but this would require the user to click 4 times rather then just once.
Im working with a DataGridView with an imported CSV file where the values are delimited with (,).. The grid works perfectly fine. My ultimate goal is to hide the grid out of view from the user and access the data in the grid based on the coordinates of the grid specified i.e (The cell in column 5, row 6 contains the value "Taco") and I want to save that value to a variable...Eventually I want to loop through all the values of a column and save them to individual variables to be later used. So far, this is what I have...
Dim sReader As New StreamReader("book1.csv")
Dim Record() As String
For x As Integer = 0 To 17[code]....
Presently, that will only display the data in column 0, row 0 in those labels...
Note: 17 in the for loop is the amount of columns in the data i provided.. that number will never change.
