.net - How to populate a WPF grid based on a 2-dimensional array

You can populate a WPF Grid based on a 2-dimensional array by dynamically creating and adding UI elements to the Grid. Here's an example of how you can achieve this:

Assuming you have a 2-dimensional array like this:

int[,] array2D = new int[3, 3] { { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 } };

You can populate a WPF Grid like this:

<Window x:Class="YourNamespace.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Grid x:Name="myGrid"> <!-- Grid will be populated dynamically --> </Grid> </Window> 
using System.Windows; using System.Windows.Controls; namespace YourNamespace { public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); PopulateGrid(); } private void PopulateGrid() { for (int i = 0; i < array2D.GetLength(0); i++) { for (int j = 0; j < array2D.GetLength(1); j++) { // Create TextBlock TextBlock textBlock = new TextBlock(); textBlock.Text = array2D[i, j].ToString(); // Define Grid Row and Column Grid.SetRow(textBlock, i); Grid.SetColumn(textBlock, j); // Add TextBlock to Grid myGrid.Children.Add(textBlock); } } } } }

In this example:

  • We create a 2-dimensional array array2D.
  • In the PopulateGrid() method, we iterate through each element of the array and create a TextBlock for each element.
  • We set the Text property of the TextBlock to the corresponding element value.
  • We set the Row and Column of each TextBlock in the Grid using Grid.SetRow() and Grid.SetColumn() methods.
  • Finally, we add each TextBlock to the Grid by adding them to the Children collection of the Grid.

This will dynamically populate the Grid with TextBlocks based on the elements of the 2-dimensional array. You can adjust the layout and appearance as needed.
