DataGridView inserting an extra row every time I populate with data. The row appears even if I only fill the column headers. This is causing problems when I try to get values of each cell. Is there a way to avoid this perhaps in properties?

I'm new to VB 2008 and was wondering how to apply 2 toned back color to my datagridview column headers or listviews. Where the color is lighter at the top of the column header and then becomes darker towards the bottom of the column header. It seems most apps use them these days.

I am developing a project using VB2010. In the attached example I created a Form.
On tha form I put a GroupBox Containing a DataGridView.
I am trying to set, at Design time, the ColumnHeadersDefaultCellstyle Font of the grid, defining the Font, the size and the style (Bold). After saving the project or running it, The Font properties of the grid headers are changed to the Font properties of the containing
GroupBox.
Why is that so? How can I set, at Design Time, a different font for the Grid Column headers and the GroupBox?
To demostrate the problm - Try to modify the Font of the grid headers, in the attached example,
to "Bold" "Size 12", Run the application and see the result.

VB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.

I have a csv file that is being sent to me in this format[code]...
This is the only way this file can be exported from the system that is sending the information.
The second item is the Header and of course the 3rd would be the value that needs to be inserted into the row. How do I import a file like this. It is going to be sent to me every 5 minutes so I have to be able to extract the data shortly after the file arrives and insert it into Sql server.

What I'm trying to do is parse a CSV file that has column headers, and map those headers - ideally to a class.The tricky part is that I need to be able to support various mappings because it will be interacting with different systems that give the headers different names. Additionally, being able to combine fields would be extremely helpful.
Fortunately, the CSV will always be correctly formatted with all fields encapsulated in double quotes.

But I would like to change it, so that each question is a header, like this:

This makes it more readable since each user is only listed once.I would like to stick with a gridview instead of rewriting all my code.I am actually binding my data to the gridview via some other programmers class. I am using LINQ like this:

I need to create a checkedlistbox that has multiple columns and each column has a header. Is this possible? I can't really find much on Google. Here's the headers I need:
Checkbox Title Existing path Destination path
I have created these columns to the checkedlistbox I have in my form, but when it is run the headers don't show up. Also the items I'm adding don't seem to abiding to the column widths I put in. Also with the code I'm providing below the items don't display as multiple rows, meaning each item doesn't get displayed on a new row, but in a new column.

For i = 0 To iMovies
Movie = New MovieItem()
Movie.tmdbid = CInt(StrBetween(moviestag, "<tmdbid>", "</tmdbid>"))

I am using VB.net 2008 express edition. I have figured out how to use some of the code snippets for the open xml sdk to create a drop down list of all the sheets in an excel file. I can also use the code snippet to get the value of an individual column header. What I want is a drop down list of all column headers. I could create an array containing the alphabet and loop through each column based on the alphabet letter in the array. I would then just exit the loop on the first column with no value returned for column header...but there must be an easy way to return all headers in one query of the xml.

I have created a Stored Procedure in SQL which produces a pivot table. I've successfully created a GridView in ASP.NET to display this data.
However, some of my column headings are dynamically generated from the data (AutoGenerateColumns=True), and those column headings are just dates, so they will look different almost every time the table is generated.
This all works fine, except that the date format of the column headings is wrong. I know I could change the way SQL produces the dates in its output, but I don't want to do it that way. I want to control it from the web page.
I didn't think this would be difficult - I thought I could just do something along the lines of finding the cells in the header row and changing the datastringformat. The problem is that whether I put my code in the GridView's DataBound or RowDataBound event, the cells in the header row seem to be empty, so I can't reformat them. It's as if the headers get populate some time AFTER the DataBound event, but I don't know when or how to trap it.

I am trying to change the forecolor and backcolor of the column headers in a ListView and I have been able to change the background color; however, now the text has disappeared (the text that shows up in the column headers). How do I go about specifying Color.Argb(193, 218, 248) as the text color? Please advise as I have searched all night online and have not been successful as of yet.
This is what I am using right now:
