Exporting Data To A DataGridView Using A 2 Dimensional Array?
Feb 3, 2009
I have a problem on Data Grid View.Actually, i need to transfer data from a VB 2005 form by clicking on the form which consist of a two dimensional array grid - Infact the form will consist of a picture on which a 2 dimensional array grid, which would represent the various coordinates on the map. The user will have to click on the points on the grid to export those results to the x an y coordinates on a datagrid view.

I declare 2-dimensional array at class level
Dim delItems(9, 9) As String
The array elements are then each set to "EMPTY". I create a new form in memory
Dim frm As New Form
I create a new DataGridView add columns to it and add it to the new form
Dim d As New DataGridView
frm.Controls.Add(d)
Now the problem.....this code give error when try to load contents of 2-D array into DGV:
For i As Integer = 0 To 9
d.Rows.Add()
For j As Integer = 0 To 9
d.Item(i, j).Value = delItems(i, j).ToString
Next
Next
Error is ArgumentOutOfRangeException (Index was out of range...)
When I check value of loop control variables, i = 0 and j = 1

I need some advice to accomplish this, i have a datagridview with this data:
Column1 Column2
item1 3
item2 1
item1 2
item1 5
item2 3
item3 1
item1 3
I need an array with distinct values of column1 and the sum of the values in the second dimension of the array: ar(item1,13), ar(item2,4),ar(item3,1).
I don't know how many items i will have, so i don't know the correct dimension of the array...

It creates strings just fine, but when I go to save it (writeline) it breaks.

I am using Visual Studio 2008 and looking for an efficient and hopefully straightforward approach for exporting data from a DataGridView to Excel. If doable, my preference would be to export the data to Excel without instantiating an Excel application. I found some code on the Microsoft support site that is fairly accessible but the example shows how to export just a few pieces of data. Would someone be able to demonstrate how to modify this code to so that it could be used for large amounts of data (for example, data from a DataGridView).

What I'm looking for is a snippet on how to export data from a datagridview to an access DB. My other question is fairly simple what code would I use once the data has been entered to account for the addition/subtraction. I know these are fairly
simple questions with probably incredibly easy answers, but once again the first time I've picked up a programing language was a week ago. Hey trial by fire works 70% of the time all the time.

I have a 2 dimensional array 'allData(100,2) Is it possible to write the values from this 2-dimensional array to a csv, without using loop?
currently, I have a code but it uses Interop. Unfortunately, I need to just use csv because our servers does not support Interop. Here is my code when using Interop:

I want to export data from a DataGridView to a CSV/text file. I then also want to be able to load that same CSV/text file and populate that same DataGridView at a later point in time. My information is loaded into columns in the DataGridView. That is, I am not using rows to represent records, I am using columns. As such, I need to load all the data in each column and export this, by column to the CSV/Text file. Likewise, when I load the control from the CSV/text file, I need to load each column with this information.How do you export/import from/to a DataGridView controlHow do you organize the data in the CSV/File

I have a string containing many lines. Each line has many values separated by commas. Basically it's in CSV format. The number of lines is variable but the number of columns is always 7.
I can get each line into a one dimensional array using Split(Var, Chr(10)).
I'd like to make it a two dimensional array where the second dimension contains each comma separated value.
I've got
Dim VarArray1() As String = Split(VarText, Chr(10))
Dim VaryArray2(0 To VarArray1.Length - 1, 0 To 6) As String
Is there a quick way to get the contents of VarArray1 into VarArray2. I know I can do the following.
For Counter = 0 to VarArray1.Length - 1
Dim line as string = VarArray1(Counter)
Dim Values() as string = Split(line, ",")
For Counter2 = 0 to 6
VarArray2(Counter,Counter2) = Values(Counter2)
Next Counter2
Next Counter
But is there a quicker way to do it that doesn't require passing through each element of VarArray1 and then passing through each element of Values.
The eventual goal in all of this will be to find the highest value in the 3rd column (the arrays are strings at this point because not all columns are numeric). To do that once I get the values into VarArray2 I suspect I have to pass through each element VarArray2, i.e. VarArray2(Counter,2). Unless I can copy the whole third column into a SortedList?

I have a datagridview(DGV) which contains data based on a user selections from a pre-defined dataset
In point form:
User starts program
program builds datatable
user opens file and program read all data from file into the dataset.datatable
user defines the data they want to see
program displays datagrid based on dataset.datatable and user choices. (basically it displays the whole dataset and removes unwanted columns
ecords)
I want to be able to export the datagrid to excel (not sure which method yet). I have tried the excelexporter component i found somewhere on the msdn forums (it exports the data to look exactly like the datagridview) but its painfully slow. It exports something in the region of 100 records per minute. Most of the time, the datagridview can contain anywhere from 3000-32,000 records. As such, at 100 records per minute, the excel generation can take updwards of 50minutes. Unacceptably slow for the purposes of the program.
What do people recommend as the best method to quickly dump the contents of a datagrid into excel. By quickly, im talking at the speed of about 10,000 records per minute. In all honesty, anything over 5000 records per minute will be fast enough, but the quicker the better!
Is there a way of creating a new dataset.datatable that is built of the contents of the datagridview and then building an excel sheet by connecting to the new dataset?
I would like to be able to export to Excel 2000-2003 at a minimum, but if i can do excel 97 as well it won't hurt.

I am filling a datagridview with very lengthy results. Roughly 60k rows on average. I am filling them via an oracle database using a table adapter. The records then have a filter placed on them in the datagridview so the results displayed are a bit different.
My problem: I built an export to excel function which populated a dataset and then red through it and wrote to excel. Bad idea with the amount of records I am using. I tried just writing the records straight to a csv file using streamwriter but I don't very much like this way.
My proposal: I would like to fill an array from the datagridview and then be able to dump the array into excel. However I am having some trouble finding examples on creating an array from a datagridview.

I'm using this to export an unbound datagridview to a csv:
Private Sub subExportDGVToCSV(ByVal strExportFileName As String, ByVal DataGridView As DataGridView, Optional ByVal blnWriteColumnHeaderNames As Boolean = False, Optional ByVal strDelimiterType As String = ",")
Dim sr As StreamWriter = File.CreateText(strExportFileName)
Dim strDelimiter As String = strDelimiterType

It works great but the only thing it doesn't write is the column headers. I can't figure out why it won't include them in.

Now my DGV has records in it and I try to export it to Excel File. Now it exports the the Column Names above but none of the records. My code is below.
Dim fs As New IO.StreamWriter("C:exported.xls", False)
fs.WriteLine("<?xml version=""1.0""?>")
fs.WriteLine("<?mso-application progid=""Excel.Sheet""?>")

I got this code from the MSDN forums from a link someone posted. They said they changed IntCol and it worked to incoude the records as well but I cant figure it out. When I hit Export it does prom,pt me to save the file and saves the Names above to excel sheet but none of the records.

I've been working on a VB project where I use a 1st drop down list to select a movie category and then in the 2nd drop menu, movies from that category will be displayed. The movies are stored in a 2-dimensional array by category. I've been able to edit my array but I'm having problems with my .AddRange() function. What would I have to put in those parentheses for the list (for each category) to appear in my 2nd combobox when the category is selected?

For my programm I am supposed to store the minimum points in a five-element, one dimensional integer array name points. And I need to store the grades in a five-element, one dimensional string array named grades. These arrays should be parallel arrays. I am supposed to code the display grades button click event procedure so that it declares both arrays. It also should search the points array for the number of points entered by the user, and then display the corresponding grade from the grades array.
