根据 WPF 中的索引在 UniformGrid 中查找子行和列 [英] Finding a childs row and column in UniformGrid based on Index in WPF

问题描述

在 WPF 中，我有一个统一网格，希望能够根据子元素的索引找到行和列.

In WPF, I have a Uniform Grid and would like to be able to find the row and column based on the index of a child element.

我知道有一种数学方法可以做到这一点，我宁愿不使用普通的网格.

I know there is a mathematical way of doing this and would rather not use a normal Grid.

如果有帮助，我可以使用以下方法获取行和列的总数:

If it helps, I can get the total number of rows and columns by using:

Math.Sqrt([*uniformgrid*].Children.Count)

推荐答案

抱歉，这是在 C# 中，但原则上您需要这样做

Sorry this is in C# but in principle you need to do

int rows = theGrid.Rows;
int columns = theGrid.Columns;

int index = theGrid.Children.IndexOf(childElement);

int row = index/columns;  // divide
int column = index%columns;  // modulus

在 VB.NET 中

dim rows as Integer = theGrid.Rows
dim columns as Integer = theGrid.Columns
dim index as Integer = theGrid.Children.IndexOf(childElement)

dim row as integer = index \ columns
dim column as integer = index mod columns
