Change text color in datagrid (windows form) depending on value of other column

Hi,

I have a datagrid where I display some columns.  This datagrid is based on a dataset, one of the columns of this dataset is Color, where the numerical value of the color is stored (e.g. 255 for red).  My question now is : how can I set the fontcolor of my columns to that stored column.  I have already created a class 'ColoredDataGridColumn' that I inherited from DataGridTextBoxColumn, and I created a sub Paint in the class:
Protected Overloads Overrides Sub Paint(ByVal g As Graphics, ByVal bounds As Rectangle, ByVal source As CurrencyManager, ByVal rowNum As Integer, ByVal backBrush As Brush, ByVal foreBrush As Brush, ByVal alignToRight As Boolean)

My problem is now : how do I know the color that is stored in the column ?

I already examined the code that changes the background to pink if the first character is bigger than "F", and this works, but this is a very static test.

Thanx,
Andy

Can you please give some more examples of some numerical values of the color that you want...
I never tried to do exactly this, but since you've based your column as a TextBoxColumn, you might have a MyBase.TextBox.Text .

That's where I expect your color value to be.

Hi Juravich,

The color itself is not the problem, I can convert a color as 255 to color.red with ColorTranslator.FromWin32(255). The problem is to know the value of the color when painting another textbox

You can get the color from the brush.

I know how to set the color of each colomn if I use a fixed test (e.g. value < 0), but not if the color depends on the value of another column.
What are you asking for?

I have a dataset which contains several columns, one is called 'fontcolor' and contains a numeric value for the color (e.g. 255 = color.red).

I have a datagrid based on this dataset, in which I display several fields (not fontcolor, other fields). I want the value of the fields (datagridcolumn) to be displayed in the color that is stored in 'fontcolor'. The problem is not to convert 255 to a systemcolor, but how to know the value of 'fontcolor' in the 'paint' event of the datagridcolumn (actually a descendant of datagridcolumn).

Basically:
I have a set of orders, and each order has a specific status (created, picked, shipped, ...), and each status has a color (the user can choose this color). So when I show a list of the orders, I want each order (=1 line in datagrid) to be displayed in the color of the orderstatus .
Are you asking for a way to associate the "FontColor' value column with the actual colored DataGrid column?

Yes, I want a way to 'color' the datagrid column text with the color specified in another column

In this case, I was setting MaxValueColumn to another DataGridTextBoxColumn that had a value that I needed to test against.  In the Paint event, I get the value from the cell, and compare it against the MaxValueColumn's value to define different brushes for the cell.
