How do I set the color of a particular column in my C# winforms datagrid?

Thanks,
Dave
 
It's really easy if you're using Visual Studio. Right click on the DataGrid and go to the property builder. Click on the format tab and under columns in the tree view you can set all properties for different columns or all at once.
 
I should clarify, It's a windows forms app, visual studio 2002, populated in
the code below.

I don't know what the syntax is for setting the column color of a specific
column (for example, when i=2, I need to column color to be gray). I don't
think the property builder is available in this situation (is that just for
web apps?).

Thanks,
Dave


DataGridTableStyle tableStyle = new DataGridTableStyle();
tableStyle.MappingName = "Defs";
DataTable dt = dsDefs.Tables["Defs"];
for(int i = 0; i < dt.Columns.Count; ++i)
{
DataGridTextBoxColumn TextCol = new DataGridTextBoxColumn();
TextCol.MappingName = dt.Columns.ColumnName;
TextCol.HeaderText = dt.Columns.ColumnName;
tableStyle.GridColumnStyles.Add(TextCol);
}
dataGrid1.TableStyles.Clear();
dataGrid1.TableStyles.Add(tableStyle);
dataGrid1.DataSource = dt;
 
Dave,

You should create a derived DataGridColumnStyle (most likely inherited from
the DataGridTextBoxColumn) and override its Pain method to alter the
background color depending on the cell value.

MSDN has a very good article on customizing the DataGrid, try searching for
the "Customizing DataGrid" keywords.
