Importing Data From Excel To Datagrid Or Datagridview?
May 5, 2010
I have a problem loading big spreadsheets into a datagridview.
I had a similar code as above that i used and it works great if you have say 10000 cells to populate cell by cell.
How ever moving to 2 mil cells is a different cup of tea, the code took more than 7 minutes to load the data, and although the data was perfect in every way, its too time consuming, i cant get it to work faster so I used the datagrid instead.
The sheets needed to be imported is 350,000 cells plus. I used code that works realy great, does the import into the grid and transfers the data to a datagridview within 15 seconds with little resources which put a smile on my dail :) then i saw something and it dropped ...
see code:
[Code].....
My problem is that whenever there are values below the heading of the cell the datagrid displays (null)
No matter what i do even converting the values in excel to text it does not display the heading of that column.
When i paste other text into the cells below the heading (NOT NUMBERS) it shows the data and heading, Only if the "type" of content is the same does it display both the heading and the text that follows in rows below.
I would like to Import data from multiple sheets in a workbook. With this following code I get the this error: "The MS Jet database engine could not find the object 'Sheet1$' Make sure the object exists and that you spell its name and path name correctly." The name and path are correct, the error ocures in the highlighted statement. The sheet name is Sheet1

I have imported a set number of rows (17) into a DataGridView but how do im import like for example thousands of rows? Am i suppose to have thousands of code lines to import row by row?!

I am importing data from Excel to a datagrid in VB, I can get the data on there no problems and also save this back to a SQL database without any problems.
However I have a new spreadsheet which has the same product listed again and again with the same description but different totals, what I want to do is to upload this to the datagrid just once for each description, with a grand total of all the seperate totals
I am trying to import data from a server and put it into an excel sheet. I have included (imported) the Microsfot.Office.Interop package into my program. I have been looking through the Object Browser to find the correct commands to add this imported data. Should the ListColumns.Add and Listrows.Add functions be used in this spot? I have started a code however, it was initially going to be used with human interaction. The new direction is to make it automated. The section of code I have written follows:
#Region " (Import Data) This function will import the PI Tag Names and desired Attributes into an Excel worksheet " Private Sub Import()
[Code]...
After the nvs.Add("changer", 1) there are many more attributes that are going to be added to the excel file but I did not feel they needed to be shown here.
I have been trying for several months (in my spare time) to write a vb.net (version 2010) program that connects to Excel (version 14) and imports numerical data.This data will be used later for engineering calculations.I have tried the Interop code which I have found on the internet with limited success and now I am trying the connection string method.I have found some examples of code, on the internet,that I have pieced together and can't get it to run.Below is that code.
Imports System.Data.OleDb Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click[code].......
This is a screen image of the error I get when trying to run the program.
I need to import data from Excel worksheet into the VB.Net program. First, I need to get the data to some array or arraylist and secondly to show the data to user through datagridview or similar.So far, I have this
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim myDataset As New DataSet() Dim strConn As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=C:TempTest.xls ;" & "Extended Properties=Excel 8.0;"[code].....
How can I adjust the code to manage that? And how can I import the same range to variables (the range contains approx. 200 rows and 30 columns of data points) and I need the flexibility to add or delete items (rows) from the data in memory later.

Is there a routine that will allow me to import data from an excel spreadsheet into a database within my project? I only need to do this to populate the the database I have created in my project.
While the project was being developed I used junk test data for testing and debugging but now I wan to populate the database with the actual records.
Here is the skinny:
In the project database I have the following fields: ItemID - Primary key SamCode
[Code].....
Column B contains the Full Name Data where B1 in a column header Column C contains the UPC Numbers needed where C1 is a column header
As stated this is a one time deal and not something I need to run as part of the application.

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 am trying to make part of a form program do the following When I exit a text field, I want to import some datainto a datagridview control.The columns are (1)Key, (2)Location, (3)Part Number, (4)Serial Number, (5)Description.There are up to 1000 rows of data in anyone of the spreadsheets I am working from.By using a datagridview, I can click the header and sort the data by either of the 5 columns, and when I select a data row, the Key number is reported back (for now, into a text box)I will be using the key number to further manipulate the spreadsheet after I have solved this problem.There are thousands of articles on DataGridView, and over the past 8 days, I think I have read them all. I have tried many downloadable routines, which haven't populated the DataGridView at all.Please can someone show me a simple program which will do the above task, and will give me a base to start from.I am running MS Office Pro plus 64-bit on Windows 7 and Visual studio 2010 pro
i want to binding excel data to a datagrid without no header, just the data.for example :my excel files consist of 3x3 matriks data in 3x3 excel cell like this
1 2 3 4 5 6 7 8 9
and i want to show all this data on data grid i have tried with some code like this
Dim MyCommand As System.Data.OleDb.OleDbDataAdapter Dim ds As New DataSet MyConnection = New System.Data.OleDb.OleDbConnection("provider=Microsoft.Jet.OLEDB.4.0; " & _
[code]....
but the first row of that data ( 1 2 3 ) is not shown up in the datagrid, just the 2nd and the 3rd row that shown up in datagrid?
I am working on exporting some data to a DataGrid (with no luck). So far I have:
[Code]...
When this runs, I get an error message that says: System.Data.OleDb.OleDbException: The Microsoft Jet database engine could not find the object 'Sheet'. Make sure the object exists and that you spell its name and the path name correctly. The excel file has only one sheet that is named "Sheet", and the location specified in the connection line is correct. Any ideas on why this may be happening?
This code works well however when data is exported to excel in one field some values are wrong. Instead for example populating 16-12-19 it populates 43815, 01-03-99 it populates 36220. Again, if the sort code is like 20-72-68 or 60-01-22 it is populated the same way, which is correct. If the value is a date lookalike then this problem appears, but if not then the exact value as displayed on the grid is shown in excel.
I inserted the code (highlighted in red) to set all the fields as text values. Right, it is exported and when excel spreadsheet is opened the field property is text, but the problem still exists. Why doesn't excel display it as it is displayed on the datagrid and database, instead of changing it even when set text.
I am working with Vb.net and this code below works fine. However, when I review the data exported to excel I have a problem with one particular field i.e., sort code. Sort code in the database is in the format 00-00-00. Therefore if it is 12-11-09 or 11-01-66, a look alike of a valid date it is disaplyed as 12/11/2009 and 11/01/1966 in excel after the export. Excel thinks its a date which is incorrect. I expect it to show 12-11-09 and 11-01-66.

I'm new to vb.net. I cannot save data from datagrid to excel. I use inputbox so user can input data to datagrid. Then the user can click the button to save it to excel.
