Answer 1

These are 2 methods that can be used to take a value from the selected row

    /// 

    /// Take a value from a the selected row of a DataGrid
    /// ATTENTION : The column's index is absolute : if the DataGrid is reorganized by the user,
    /// the index must change
    /// 
    /// The DataGrid where we take the value
    /// The value's line index
    /// The value contained in the selected line or an empty string if nothing is selected
    public static string getDataGridValueAt(DataGrid dGrid, int columnIndex)
    {
        if (dGrid.SelectedItem == null)
            return "";
        string str = dGrid.SelectedItem.ToString(); // Take the selected line
        str = str.Replace("}", "").Trim().Replace("{", "").Trim(); // Delete useless characters
        if (columnIndex < 0 || columnIndex >= str.Split(',').Length) // case where the index can't be used 
            return "";
        str = str.Split(',')[columnIndex].Trim();
        str = str.Split('=')[1].Trim();
        return str;
    }

    /// 

    /// Take a value from a the selected row of a DataGrid
    /// 
    /// The DataGrid where we take the value.
    /// The column's name of the searched value. Be careful, the parameter must be the same as the shown on the dataGrid
    /// The value contained in the selected line or an empty string if nothing is selected or if the column doesn't exist
    public static string getDataGridValueAt(DataGrid dGrid, string columnName)
    {
        if (dGrid.SelectedItem == null)
            return "";
        for (int i = 0; i < columnName.Length; i++)
            if (columnName.ElementAt(i) == '_')
            {
                columnName = columnName.Insert(i, "_");
                i++;
            }
        string str = dGrid.SelectedItem.ToString(); // Get the selected Line
        str = str.Replace("}", "").Trim().Replace("{", "").Trim(); // Remove useless characters
        for (int i = 0; i < str.Split(',').Length; i++)
            if (str.Split(',')[i].Trim().Split('=')[0].Trim() == columnName) // Check if the searched column exists in the dataGrid.
                return str.Split(',')[i].Trim().Split('=')[1].Trim();
        return str;
    }
