I have a DGV with several columns in it displaying some data. I want to be able to have certain rows in the DGV act as category headers to provide separation of the data. The category header should be a row that has one column that extends the full width of the DGV. How can I create this mix of single & multicolumn rows within the same DGV?
View 2 RepliesWell, the title pretty much says it all. I have a user control that is a a collection of six label controls. three are used as visual color indicators, and the other three are used as the corresponding value for each color indicator. (It's sort of like a legend key on a chart or map.) I have created a custom class to store the three values, and the associated methods to interact with the values. (I can probably use a structure instead of a class, but right now, I don't want to discuss that.) My problem, is that I want to show my user control inside a cell of a DataGridView. I've looked at the examples that create a MaskedTextBox DataGridViewCell, but I can't seem to get it to work. Here is what I have:

I came across this great article on creating a custom datagridview column which creates a graph-like effect in the cells of a custom datagridview column:[URL]..Does anyone know how you would edit this to format the number in the cell as a percentage? And does anyone know how you would set this up to take 0 values which do not create any graph effects at all.I have been trying to do this but keep getting errors.

I'd like to save all the information to a 'new' database file. how to create a database on the fly, once that is done i'll be able to connect to it no problem, but actually creating the file is proving difficult to work/find out.
Also, with vb.net and the newly created custom file, how can it be made to automatically open that information with the program?
Is there a method in installation to associate the file type with the new program? How can i check when the program loads if a database file has been 'double-clicked' (rather than just running from the .exe of the program) and proceed to load the data?
EDIT1 - Extra InfoThe windows application has many different fields and content etc, then i need to save that to a file that could later be loaded by 'double clicking'. I assumed the easiest way would be to create a mini-database for each unique file

I need two seperate lists, which every item is Integer, String, Bitmap - and one which every item is Integer, String String. However I don't know how to do this, or even where to look - I've googled for custom objects and custom object lists. What I'm trying to do is this.Custom Object1 is Integer, String, Bitmap Custom Object2 is Integer, String, String
In one thread I'll be adding items to List1(Of Object1), and processing them, and adding the results to List2(Of Object2), however I need to be able from other threads to look at the list and say only give me the items where Integer = (my thread ID), is this possible? Any help, or even links to information that would be relevant to this request would be helpful?

View 2 RepliesI'm trying to create a custom DataGridViewColumn and DataGridViewCell, and have found this article to be a great resource. I'm done creating the DataGridViewColumn class and the DataGridViewCell class, however, when I try to edit the type of the column, my new custom classes don't show up as one of the options. My DataGridViewScheduleColumn inherits DataGridViewColumn, so I'm not too sure what I'm doing wrong. Is there anything else I need to do to expose these classes to the IDE?[code]...

View 6 RepliesI've been working with this for a while now and have finally come to you for help. I have a custom control that inherits from a label and I'm trying to use it in a datagridview. I have followed this example and have tried to adapt it to my needs.
The custom control in this case is a label with a boolean type property named Value. When value is true, the label.text = "ON" and the color is red. When value is false, the label.text = "off" and the color is transparent. This is the effect I need to show in the dgv.
I have attached my developing project and would like you to take a look if you can. The project has a single form with the dgv, the custom control and a button on it. When the button is clicked the value of the custom control toggles. The control on the form changes color and text as it should, but the cell in the dvg simple changes text from FALSE to TRUE.
So I know this will end up being a hard task, but I want to figure out how to do it. My language won't be outrageously sophisticated. Here is an example of what it'll do[code]...

The best analogy of what I want to do is to create a custom dialog box, but obviously instead of returning a simple integer I'd be returning a dataTable.
