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'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?
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)
so i need someone correct my coading to insert data from text field into database mssql... below is my coading;
Protected Sub btnSimpan_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSimpan.Click
Dim dtTemp As New DataSet

what 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.
View 22 Replies1) How can I load data from Text file to DatagridView. I want it because I'm making a listener. And when I load a data from text file, i want to edit rows. And this calling the second question.
2) How can I save data, Datagrid to Text file.
I found a code
Dim obj_oledb_da As System.Data.Odbc.OdbcDataAdapter
Public Function ConnectCSV1(ByVal filetable As String) As DataSet
Dim dataSet As New DataSet
[Code] .....
I can load data with this code but I can't save.
My Text File must be like this:
#IP
127.0.0.1 localhost
I have Vb 2008 and Ms access 2007, I tried this code to show the data in Datagridview but didn't do any thing and didn't show any error. [Code]

View 1 RepliesI'm making an autotyper/spambot, these may seem wrong to a few or most of you but it's a $50 bet to me. But anyway, I have the controls on form 1, (TextBox1 + Start + Stop (user input), ComboBox1 + Start + Stop (For pre-defined input.)) and the pre-defined text on form2. But I have a problem with the combo box reading the data on form 2.
Example:
On timer2_tick
Sendkeys.Send(Form2.textbox1.text)
I am trying to retrieve data row by row from my SQL Server and load them into my respective textboxes, I was doing the below code but of course it doesn't work as the For Each loop will load every single textboxes with each data retrieved, ran out of ideas.

Dim cmd As New SqlCommand

no beating around the bush, here's the code.

I have a window application develpoed in vs 2008, framework 3.5, in which i have put a button.. Now where i click that button the other text boxes are filled up with the data from database thru web service.. what i want is while all text boxes are being filled i want to show an animated loading gif image till data loading is completed in all the text boxes.. i have tried to use image picture box but while data is loading gif image is displyes but in static mode.. cant see animation... i think this is because data loading and animation both are done thru one UI thread..
View 8 RepliesI have two datagridview's both are databound. First one shows items for sale and the second stores all the items that were sold. I am trying too transfer selected rows from one to the other but no matter what I keep getting told "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound."
View 2 RepliesI am trying to get my datagridview to display more than one row of data.Every time I call the program it only writes the 1st line of data in the datagridview instead of adding it to a new row.I have been looking on the forums for hours but combined with my inexperience I can not understand it. The following code is in a loop and it reads an xml file each time.The goal is to put the xml data from each file into a new row in the table.Public Sub ReadData(ByVal filename As String, ByVal file As String)Try
DS.ReadXml(filename)

View 9 RepliesI found a sample of how to display data from a table in to a datagrid using VB.
con.Open()
Dim reader As SqlDataReader = _
cmd.ExecuteReader()
DataGrid1.DataSource = (reader.GetSchemaTable())
reader.Close()
But this just displays the details of the table columns. For example row 1 has details about usrID, row 2 usrTel ect rather than the actual data of the table.

Why does it only print all the rows for each DS (different sizes/colors) only if there are more then one DS? (if there is only 1 DS it will only print one row, regardless of different colors/sizes but if there is 2 DS, it will print all the values from the first DS)I have gotten a massive headache from trying to figure out these 2 problems. If any1 can help I would be very grateful. Please let me know if you need anymore info (SQL tables, data), and I'll put them up.
how to print the data in my text box and datagrid.
This is my form: If i click, the Print Button, a receipt will be printed with all the data in the text box and datagrid.
I have a CSV file which I append using the LoadActivityLog sub and then I pass this CSV to a datatable and populate a DataGridView in my form using the WriteAcitivityLog sub. Everythign works fine. However the datatable passes the information into the datagridview in such a way that it populates the column header rows with data as well. I want to put custom column header fields into the datagridview. However i cannot figure out how to do this.

I am using Datagridview to show some table data from database. It is working but its appearance is not what i am looking for.Is there a way to edit columns and rows manually ?This is a list of what i want to do :
1. First of all i want to change column captions. because they are like "Fld_name" etc.
2. There is a column that shows date. I want to write a code for it ( convert date type )
3. I want to add a button at the end of each row and write a code for it ( show detail about that record )
I have a matrix:
Module Procedimientos
Public Datos(200, 4) As String
Public Sub Inicio()[code]....
It is a Class made with the Add Windows Forms Menu.I have another Form where I added from the ToolBox the DataGridView Item.
Everything till now works like a charm, the problem comes when I try to load the matrix (previously posted) into the DataGrid. I search for the matrix via DataSource Button (from DataGrid's Properties) but I can't find it, it'll only show up the other forms. I don't know what I'm doing wrong.
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?
