How can I create alternating background colors for listview rows while only using ItemTemplate? I don't want to use AlternateTemplate because I would have to edit both of them everytime I want to change something when all I'm using it for is to create the alternating background colors. So what's a way I could do it using only the ItemTemplate?

I know that this has been asked alot on the internet and i've searched for it, but can't find any good thread/page about it.What i wanna do is:I have a listview where the user can add items to. But i want the user to able to choose backgroundcolor.The only option i can find is ForeColor, and it does nearly what i want, it colors all text on the row the user add. But as I said I want it to color the background of the row, not the text.
View 3 RepliesI have the following code. It works as is, but... I am not always going to have an even number of items in the RSS feed So, at the end of the table, I might have only one table cell on the last row. So, is there a way to count the number of ItemTemplates and AlternatingItemTemplate, so if it is an odd number I would be able to add another cell <td> </td></tr> and close the table row?

I'm attempting to do something that I know should be simple but I keep messing it up somehow. First, I'm attempting to change the font color using the color in the font dialog box, but the color will only work with the next character entered into the rich text box. Second, I'm trying to use a button to switch the font and background colors.

Different colors per line in a ListView
How can I drew Different colors per line in a ListView ?
I want to set a color on items and subitems being displayed within the listview control in a detailed view.Using the forecolor property setting would change the color of all the contents in the listview control. All I want is to display different colors on each column of the listview control. If I have four colums on the listview, it should display the contents on each column in a different color. I tried to do it on my own but it was unsuccessful. I'm looking for the exact code to set the color successfully. Currently, the code below is what I have to display the data on the listview. What line of code should I add on the code below to set different colors on items and subitems of the listview?

I am trying to create an array of colors. approach 2 doesn't work and I do not know why
Code:
'approach 1: works
Dim list As Color() = New Color() {Color.FromArgb(255, 0, 0), Color.FromArgb(0, 255, 0), Color.FromArgb(0, 0, 255)}
Code:
'approach 2: fails.. why?
Dim list() As Color = New Color() {Color.FromArgb(255, 0, 0), Color.FromArgb(0, 255, 0), Color.FromArgb(0, 0, 255)}
If instead I wish to create an array of strings, both approach works, that's weird.
I'm faced with another issue I would like to have resolved. I have filled my dataset with records from a table and successfully displayed it in a DataGrid. Next i would like to change the background color of certain rows or records in the datagrid using values from a column. E.g assuming my first column stores numeric values, I would like to have records where value in column greater than 6 have it background changed to a different color.
View 10 RepliesI am building a simple windows form (using VB.NET) for a friend to use at work. His company has about 10 specific colors schemes (they have list of RGB values) that they use for the company logo, website etc.
I want to follow this color scheme in my application and, to simplify development, would like to build an enumeration of these colors to avoid hard coding the RBG value for every label, panel etc.
My initial thought was to do the following:
Enum ColorTypes
CompanyDarkBlue = Color.FromArgB(0,56,147)
CompanyBlue = Color.FromArgB(0,111,198)
CompanyLightBlue = Color.FromArgB(0,145,201)
End Enum
However, it's not that simple as a constant is required. I looked around on the internet and I found an example of how to achieve what I need but it seemed inordinately complicated for what seems like quite a common requirement for application development.

View 17 RepliesI have a DGV with the Alternating row color set to grey.In the CellFormatting event on the DGV I want to go through the rows as if a cell contains a certain value I want to set the BackColor to red.However when I do this, it just gets overridden with the Alternating grey color. The cell in question in a normal colored row appears in red as expected, just not the alternating row.
Can I create a Pen dashpattern that consists of alternating colours rather than a solid colour followed by a space? For example:
LinePen.DashPattern = New Single() {6, 4}
creates a pattern with a dash of 6 pixels followed by a space of 4 pixels. Rather than a space, I would like a different solid colour. That way I could create a rectangular cursor with something like a black/white alternating pattern, which would be clearly visible on top of any picture.
