Set Column Size In DataGridView When Importing From A Database?
Jul 23, 2009
I'm using a datagridview to display data from an Access database. Is there a way to have the columns that are imported be set to fill up the entire datagridview? depending on what data I'm displaying the columns are either too narrow or too long for the datagridview. I'd like them to always just fill up the entire space in the datagridview without having scroll bars or empty space.
I'm creating a microwave oven this weekend. I have to import an image of a microwave oven not running, running and with the door open.What size files should I be importing. I use photo shop so I can save them as bmp's or jpgs. Should they be 72dpi? or 150 dpi? I know websites are saved at 72. ? and do I import them as jpgs or bmp's if I'm using a picture box? The microwave has to run so you have to be able to push the buttons, so is a picture box the best way to go?

I need to display an two-column editable grid not bound to a database. I took a look at ListView with Mode=Details, but it appears that only cells in the first column can be edited. I then took a look at DataGridView, and am having two issues:
1. When editing a cell, it adds a new row: [url] How can I prevent this?
2. I don't like the grey background and would like the grid to fill the whole space, right and below.
BTW, if you know of a good tutorial on using the DataGridView unbound, I'm interested. [Code]

I have a datagridview on my form with 7 columns and a variable number of rows. It's used to track stats on games (kills, deaths, assists, etc.) The way I ended up saving it was in a .xls file for the simplicity of being able to edit it in excel as well as my program. how to import the file back into the DataGridView though.
Here's the code I'm using the save the file:
VB.NET Private Sub exportExcel(ByVal grdView As DataGridView, ByVal fileName As String, _ ByVal fileExtension As String, ByVal filePath As String) ' Choose the path, name, and extension for the Excel file
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:

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 need to load an EXCEL file into my datagridview. However, my header row contains merge cells, which are not display correctly when loaded into the datagridview.

I am using Microsoft. ACE.OLEDB.12.0 as the provider with Visual Studio 2008 .NET Framwork 3.5, EXCEL 2007.
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 am a ticketing agenit in my city. i do book tickets on web of the company from which i am buying, so i have to fill a form so i want that data to be imported to my database file from that page.
It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?
