C# – WPF DataGrid: How to iterate in a DataGrid to get rows and columns

cdatagriditerationwpfwpftoolkit

How can you iterate in the rows and columns of a WPF DataGrid like with a Forms DataGridView in C#?

For example, if you have Forms DataGridView you can do something like this:

for(int i = 0; i < formsDataGrid1.Rows.Count; i++)
{
  MessageBox.Show(formsDataGrid1.Rows[i].ToString());
  for(int j = 0; j < formsDataGrid1.Columns.Count; j++)
     MessageBox.Show(formsDataGrid1.Rows[i].Cells[j].ToString());
}

Thank you for any help!

**Edit:

The reason I want to do this is that the DataGrid will be used by a user to enter certain informations in the second column of the DataGrid. Also, this DataGrid has multiple rows and I want to able to get that data and update a database with it.

dg is your XAML DataGrid x:Name

    for (int i = 0; i < dg.Items.Count; i++)
    {
        DataGridRow row = (DataGridRow)dg.ItemContainerGenerator.ContainerFromIndex(i);
            for (int j = 0; j < dg.Columns.Count; j++)
            {
                TextBlock cellContent = dg.Columns[j].GetCellContent(row) as TextBlock;
                Console.WriteLine(cellContent.Text);
            }
    }

Map<String, String> map = ...
for (Map.Entry<String, String> entry : map.entrySet()) {
    System.out.println(entry.getKey() + "/" + entry.getValue());

C# – How to convert a byte array to a hexadecimal string, and vice versa

You can use Convert.ToHexString starting with .NET 5.
There's also a method for the reverse operation: Convert.FromHexString.

For older versions of .NET you can either use:

public static string ByteArrayToString(byte[] ba)
{
  StringBuilder hex = new StringBuilder(ba.Length * 2);
  foreach (byte b in ba)
    hex.AppendFormat("{0:x2}", b);
  return hex.ToString();
}

or:

public static string ByteArrayToString(byte[] ba)
{
  return BitConverter.ToString(ba).Replace("-","");
}

There are even more variants of doing it, for example here.

The reverse conversion would go like this:

public static byte[] StringToByteArray(String hex)
{
  int NumberChars = hex.Length;
  byte[] bytes = new byte[NumberChars / 2];
  for (int i = 0; i < NumberChars; i += 2)
    bytes[i / 2] = Convert.ToByte(hex.Substring(i, 2), 16);
  return bytes;
}

Using Substring is the best option in combination with Convert.ToByte. See this answer for more information. If you need better performance, you must avoid Convert.ToByte before you can drop SubString.
