Question

I have a grid (table) like structure with rows and columns, and I am assigning the background color for every cell using the border object.

How do I change the background color for every cell of the grid?

This is my approach:

• Delete the border object and assign it a new one.

• I have also tried to create a new Border object, and add it. But it throws InvalidOperationException stating “Element is already the child of another element”.

How can I change the background color for a particular table row?

Answer 1

Now that I better understand your question…

The following code will give you the border in Row r and Column c.

var border = myGrid.Children.OfType<Border>().Where(x => Grid.GetRow(x) == r && Grid.GetColumn(x) == c).FirstOrDefault();
border.Background = [...];

Hope this helps.
