我有一个网格，我知道我用鼠标点击的地方的X值和Y值

示例：X:235，Y:235-->这应该是第3列和第3行

如何得到x，y坐标上的列和行

我真的需要添加行/列的每个宽度，直到达到所需的x/y值吗

我正在使用WPF（用于我的网格）和c#（用于x&y位置）

有人能帮我吗？

数学地板功能，例如：

Math.Floor(235/scale)
where scale is the the width or height of the grid cell.

定义：

返回小于或等于指定数字的最大整数。Math.ceil正好相反。

Math.Floor函数，例如：

Math.Floor(235/scale)
where scale is the the width or height of the grid cell.

定义：

返回小于或等于指定数字的最大整数。Ma.CeIL是相反的。

您的网格有一些背景颜色集（即使是透明的也可以）。这是为点击测试（鼠标点击空白网格区域）工作

GridSplitter

本身是网格中的成员。这一点很重要，因为单击栅格拆分器也会显示栅格拆分器所在的相应单元索引（列、行）

这里我们不关心

ColumnSpan

和

RowSpan
