I'm populating a DataGridView from a file with the following
Dim fnum As Short = FreeFile()
Dim inputLine As String
Dim i As Short = 0
Dim strAuditDate As String
Dim strAuditTime As String
Dim msg As String
[Code]...
When I do this, the MessageBox.Show shows the contents of a row, which is tab delimited. How do I get the data that I read to display in columns of the Gridview?
Loading into a Datagridview, Nothing seems to work no Error even with test data Added.
Here is some code
Dim SqlConnectionString, SqlCommmandText As String
Dim SqlAdapter As SqlDataAdapter
Dim Table As DataTable
[code]....
I have a datagridview (Unbound), which calculate several numbers, and I use this following code to save 5 of the columns to a XML file. My problem is that I would like to load this file back to my datagridview, and onlu to the same columns, without changing the rest of the datagridview.
Code used to create XML file:
Dim gridtable As DataTable = New DataTable("WaypointLeg")
Dim gridtable_collumn1 As DataColumn = New DataColumn("column1")
Dim gridtable_collumn11 As DataColumn = New DataColumn("column11")
Dim gridtable_collumn18 As DataColumn = New DataColumn("column18")
Dim gridtable_collumn19 As DataColumn = New DataColumn("column19")
[Code] .....
How I can load my XML file, and only update certain columns in my datagridview and not add 5 more columns to my datagridview? Is there a way to load the XML data to my datagridview without binding the datagridview to the XML file?
I mean without the use of the:
DataGridView1.DataSource = ds.Tables(0)
how to use datagridview. im gonna show some of my code for the connection and datagridview display

I have 1 exe and 1 dll. The dll (ClassLibrary1) file is located in the root of a website. In the dll I have a UserControl that populates with data its controls, from a database that is on a website too. The end user gets the exe file. This exe loads the dll and displays the UserControl1 on the form. This is how i load the control from inside the dll (located on the web site), on my form (exe file).

The data are fetched from the database (db is on the web) with no problem.The problem seems to be that the loaded assembly from the web (the usercontrol1 inside the dll) has no permission to access anything. I am not trying to access stuff from the user's pc (like file IO), but access a database located on a web server.
I have a window application develpoed in vs 2008, framework 3.5, in which i have put a button..

I've written the following sub to load a comma delimited file into my datagrid view but it's hanging up when it attempts to load the first two values into the cells of the datagridview. I think it's having trouble adding the cells to the datagrid. I have tried writting them directly using the .text of the specific row and cell but when I incremented to the next row it hung up because the row didn't exist (I think).

It is possible to load the DataGridView (VB 2010) with an Sql Query file that is saved in My Documents Folder?
I searhed everywhere but have not found a good reference that i can use. I have a database on SQL Server.

I want to show this report on the DataGridView. Don't know how to do it.
I generate my xml into "variable string str" by using "dataset.GetXml" and then I write the "xml which is contained in variable str" into "file.xml" by using sFile.WriteLine(str) while 'sFile' is a stream reader"My reason for using 'writeline' instead of 'dataset.WriteXml' because I need to encrypt the 'xml stored in 'str' before I store it into file.xml.I got everything fine for the encrypted result, and so does the decrypted result as well.Here's the decrypted result of my file.xml below (I have checked it the xml value which in str before encryption and which in decrypted file.xml. They are all match well)Here is my plain xml value before it got encrypted or decrypted which I stored it in variable str by using GetXml. I don't know for sure but my xml value doesn't contain declaration "<?xml version="1.0" encoding="utf-8" standalone="yes" ?>" like common xml used to have.All the xml file which I got from GetXml is just like below (No declaration like <?xml version="1.0" encoding="utf-8" bla ?>) Book 1 2010-09-22T14:43:00.0000000+07:00
And since I think it may not cause any problem then I keep coding and decrypt it which is going well and the decrypted result is perfectly same ofcourse.My problem is, when I try to make my xml value show in Data GridView by using the code below, and run the debug, it prompt an error said "could not find the file c:laFile.xml ".
ds = New DataSet
path = System.IO.Path.GetFullPath(strFileToDecrypt)
ds.ReadXml(path)

I am facing a "weird" problem with the DataGridView. In fact, I have a function, that loads each table of an xml file into a datagridview (27 tables all with same structure except one called Listes). In the datagridview I have a combobox column to select "type" (it's the 3rd Column, so it's index is 2 normally). The problem is that when I call the function loaddata for the first time, all work perfectly ! If I call it for a second time, to reload the data, I get an error of cast! I verified and it seems that first time I call the function the column that contains the combobox is column(2), but when I run it again automatically the indexes of the columns are changing and am getting the error, because the column that contains the combobox is becoming column (3) and that explains the cast error because the column'(2) is not anymore the combobox so the cast will fail ! What I can't understand is why it's reordering that way my columns automatically ?

View 7 Replieswhat I am trying to do is get a program to load data from a text file with multiple lines in the form "Name, Type, Stocklvl, Price, Location, Reorderlvl" then display it all in a data grid. From where it can be viewed and edited as well as saved back into the original file stock.txt as well as generating a separate file reorder.txt which includes data on what needs to be reordered and the date which updates on program exit. I have chosen to use datagridview something I'm unfamiliar with as I figure It'd probably be the most functional to meet my needs of displaying a lot of data clearly as much as 200 items.
