How to perform hash calculation in WinForms DataGrid?

2 mins read

WinForms DataGrid (SfDataGrid) does not provide direct support to perform the Hash calculation. You can perform the Hash calculation by customizing the CurrentCellValidated event with the SHA256 hash helper method.


//Event subscription
sfDataGrid1.CurrentCellValidated += OnCurrentCellValidated; 

//Event customization
private void OnCurrentCellValidated(object sender, CurrentCellValidatedEventArgs e)
{
     // Customize based on your requirement
     if (e.Column.MappingName == "Password")
     {
         //Get the current row
         var column = e.RowData as System.Data.DataRow;
         //Set the Password column value as SHA256 hash
         column["Password"] = GetSHA256Hash((string)e.NewValue);
     }
}

//Helper method to get SHA256 hash
public static string GetSHA256Hash(string input)
{
     using (SHA256 sha256 = SHA256.Create())
     {
         // ComputeHash returns a byte array
         byte[] bytes = sha256.ComputeHash(Encoding.UTF8.GetBytes(input)); 

         // Convert the byte array to a hexadecimal string
         StringBuilder builder = new StringBuilder();

         for (int i = 0; i < bytes.Length; i++)
         {
             builder.Append(bytes[i].ToString("x2")); // "x2" formats as a two-digit hexadecimal number
         }

         return builder.ToString();
     }
}
