在Silverlight中如何获得FlexGrid鼠标所在行列值

超级版主 / 发表于：2012-6-30 20:26 / 查看：4825 / 回复：0

鼠标在FlexGrid中移动过程中，我们可以在MouseMove中计算出鼠标所在的行、列值：

private void _flex_MouseMove(object sender, System.Windows.Input.MouseEventArgs e)
{
int row, col;
double rowHeight, colWidth;
row = -1;
col = -1;
rowHeight = 0;
colWidth = 0;
Point p = e.GetPosition(_flex);
for (int r = 0; r < _flex.Rows.Count; r++)
{
rowHeight += _flex.Rows[r].ActualHeight;
if (p.Y < rowHeight)
{
row = r;
break;
}
}
colWidth = _flex.RowHeaders.DesiredSize.Width;
for (int c = 0; c < _flex.Rows.Count; c++)
{
colWidth += _flex.Columns[c].ActualWidth;
if (p.X < colWidth)
{
col = c;
break;
}
}
this.label1.Content = string.Format("({0},{1})", row, col);
}
