DataGrid question

Is it possible to make a single cell with its contents be in red color
while the rest of the datagrid is of normal color. If so how?
Thanks in advance

You can override the DataGridTextBoxColumn and in the OnPaint method you'd
assign red as the foreground. You would need to supply the logic as to which
cells you keep as default and which you change, likely from the cell's
contents.

public class DataGridColoredTextBoxColumn : DataGridTextBoxColumn
{
protected override void Paint(System.Drawing.Graphics g,
System.Drawing.Rectangle bounds, System.Windows.Forms.CurrencyManager
source, int rowNum, System.Drawing.Brush backBrush, System.Drawing.Brush
foreBrush, bool alignToRight)
{

try
{
object o = this.GetColumnValueAtRow(source, rowNum);
if( o!= null)
{
//o is a reference to the cell's contents
//you can modify the backBrush and foreBrush to whatever color
you want
foreBrush = new SolidBrush(Color.Red);
}
}
}
catch(Exception ex)
{
ex.ToString();
}
finally
{
//Paint the string
base.Paint(g, bounds, source, rowNum, backBrush,
foreBrush,alignToRight);
}
}
}

You can download sample projects using the technique suggested in the prior
post in this FAQ.

How do I color a individual cell depending upon its value or some external
method?
