I am exporting the data in a DataGridView control using the Excel interop. It is working fine, except that it is not creating the headers. How do you include the column headers with the export?

I've google so many examples but none of them work. Well they do but they don't perform the way I need it to:
1) Check if excel file with specific file name exists in application.startup path
2) If doesn't exist, then take DataGridView contents (including header names) and write it to a new excel file
If exists, then take DataGridView contents and append to the existing excel file (excluding header names)Can someone for the love of VB.NET paste some code that can do this? I've been at it for 3 days with no sleep and nothing has worked so far I make the smallest changes to code I find online and the bloody thing doesn't work anymore. I don't know why it does that...I already have Imports.Microsoft.Office referenced to my project so I can create Excel Applications on my form.
how to add the row headers to the Datagridview? We can normally add Column headers from the Properties. But there is no option for Row headers. Can we add them through the IDE? Or we need to do it dynamically?

I want to number the rows in my datagridview. Basically the users want to know how many rows they have posted, so they can stop at a certain number.So I have done several web searches all giving the solution I came to on my own, but still nothing is showing! it's almost like there is a property I need to set to show text in the row header, otherwise it's somehow disabled or not visible, but I am not sure what!!!

View 4 RepliesIs it possible to customize the Datagridview headers format? I mean the column and row headers.
View 4 Repliesway to return letters like a,b,c,d,.......,x,y,z,aa,ab,ac,ad,.......az,ba,bb,bc,bd,.......bz, in visual basic. I am adding them to the headers of a datagridview. Sort of like excel numbers the headers on columns.
View 2 RepliesI use a datagridview where the rowheaders frustratingly stay blank after I load the form. If I modify/add/delete anything the rowheaders pop up. then when I sort by clicking on a columnheader the rowheaders become blank again. all these actions (load/add/modify/sort) go through the same refresh function. I can't seem to figure out why the rowheaders sporadically show up. they should stay visible all the time. btw, datagridview.refresh() doesn't work

I am working on a windows application using VB.net 2.0 and want to create a custom ComboboxControl which displays multiple groups. I was able to display the items in Custom combobox with headers. Below is the sample.
Header 1
Item 1_1
Item 1_2
[code]....
I want to prevent users from selecting the header items. I managed to revert back to the previously selected item if user selects the header item. Problem with this approach is drop down collapses and then reverts back to previously selected item. Is there a way to check, if the item being selected is a header item and if it is a header item, do not collapse the dropdown. Basically I want to implement behavior of HTML select list with optgroup.
1_1 1_2 1_3 2_1 2_2 2_3
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?

View 1 RepliesI 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.

I am trying to rewrite a program written in an older version of VB. The old program has a input table that looks like the one below.
1) How to I get the row headers to reflect the row line number? I have tried DataGridView1.rows(1).HeaderCell.Value = "2" but that didn't work.
2) How do I make one (or more) of the cells into buttons? Each of the cells marked "Change" and "View" are buttons.
How can I change the headers (User-Agent, etc) for my webbrowser control, not just for the first page that I browse too, but for all pages.
