Question

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.

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

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

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

Answer 1

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

And in VB.NET

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
