The color of the row in the DataGrid that is set by the value of a column

The DataGrid is really today, and the interface is confusing.

To implement a row of the. Net window DataGrid, you can set the function of the row color based on the contents of the value of a column in the row.

First, attach a connection with a Datagrid. Many features expanded solution Windows Forms Datagrid

But without the solution of my needs, I finally managed to get it done with my colleagues ' help.


To set the color of the cell by the value of a cell I won't post it, there is a solution in the connection above.
The following is a solution that sets the whole row color by the value of a column. The key is to add a DataView attribute to the custom DataGridTextBoxColumn, plus overload paint ().
When using DataGridTextBoxColumn, assign the DataGrid-bound DataView to it.

public class public class Datagridcoloredtextboxcolumn:datagridtextboxcolumn
{
Private System.Data.DataView M_binddataview;
Public DataView Bindingdataview
{
Get
{
return m_binddataview;
}
Set
{
M_binddataview = value;
}
}

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)
{
The idea was to conditionally set the Forebrush and/or Backbrush
Depending upon some crireria on the cell value
Here, we color anything which begins with a letter higher than ' F '
Try
{
Value from DataView, "ItemType" is the name of the row
String Colvalue = this. bindingdataview[rownum]["ItemType"]. ToString ();
Char val = colvalue[0];

if (Val > ' F ')//If the first letter is greater than ' F '
{
Backbrush = new SolidBrush (color.blueviolet);
Forebrush = new SolidBrush (color.white);
}
}
catch (Exception ex)
{
Empty catch
}
Finally
{
Make sure the base class gets called to does the drawing with
The possibly changed brushes
Base. Paint (g, bounds, source, rownum, Backbrush, Forebrush, aligntoright);
}
}

}

Examples of Use
Datagridcoloredtextboxcolumn Colexceptiontype = new Datagridcoloredtextboxcolumn ();
Colitemtype.bindingdataview = Dtorderitem.defaultview; Assign a table's view value
Colitemtype.headertext = "ItemType";
Colitemtype.mappingname = "ItemType";
Colitemtype.width = 90;
Colitemtype.nulltext = "";
TableStyle. Gridcolumnstyles.add (Colitemtype);
