datagrid (winform) 改变单元格颜色方法调用问题
我在程序中如何调用PaintCell()方法??
着段代码的主要功能是点datagrid的一个单元格是它边颜色
public class Form1: Form
{
protected DataGrid dataGrid1;
protected DataSet myDataSet;
private void PaintCell(object sender, MouseEventArgs e)
{
// Use the HitTest method to get a HitTestInfo object.
DataGrid.HitTestInfo hi;
DataGrid grid = (DataGrid)sender;
hi=grid.HitTest(e.X, e.Y);
// Test if the clicked area was a cell.
if(hi.Type == DataGrid.HitTestType.Cell)
{
// If it's a cell, get the GridTable and ListManager of the
// clicked table.
DataGridTableStyle dgt = dataGrid1.TableStyles[0];
CurrencyManager cm = (CurrencyManager)this.BindingContext[myDataSet.Tables[dgt.MappingName]];
// Get the Rectangle of the clicked cell.
Rectangle cellRect;
cellRect=grid.GetCellBounds(hi.Row, hi.Column);
// Get the clicked DataGridTextBoxColumn.
MyGridColumn gridCol =(MyGridColumn)dgt.GridColumnStyles[hi.Column];
// Get the Graphics object for the form.
Graphics g = dataGrid1.CreateGraphics();
// Create two new Brush objects, a fore brush, and back brush.
Brush fBrush = new System.Drawing.SolidBrush(Color.Blue);
Brush bBrush= new System.Drawing.SolidBrush(Color.Yellow);
// Invoke the Paint method to paint the cell with the brushes.
gridCol.PaintCol(g, cellRect, cm, hi.Row, bBrush, fBrush, false);
}
}
}
public class MyGridColumn:DataGridTextBoxColumn{
public void PaintCol(Graphics g, Rectangle cellRect,
CurrencyManager cm, int rowNum, Brush bBrush,
Brush fBrush, bool isVisible){
this.Paint(g, cellRect, cm, rowNum, bBrush, fBrush, isVisible);
}
}
